Muscle & joint pain due to tamoxifen?

Hi everyone I am a cancer survivor I was diagnosed with breast cancer in July 2011. I had my lumpectomy in August of that year got the all clear on the 13th September 2011 & started my radiotherapy in November finishing in December. I started my tamoxifen once all of that was over & I must admit I thought I was pretty lucky to have got away with no side effects however about 6 months later I started with muscle aches in my calves & aches in my knee joints & neck then it pretty much spread to all of my body , then I was diagnosed with fibromyalgia but on speaking to various people I think it’s tamoxifen I’ve been on it for 8 years now & I feel like it’s time to come off also the hot flashes are a nightmare. Does anyone else have similar symptoms to mine I love to hear from you 

  • To apples you can only judge by your pain levelsspeak to your oncologist nurse let them know what’s going on from what I’ve read tamoxifen has benefits of up to 15 years cover when you’ve taken it for 5 years but they are not sure about the amount of extra coverage you get with 10 years as they have only started asking people to take it for 10 years recently take care

  • Hi dawn

    check in with your oncologists & tell them how you feel.I am exactly the same feeling like an old woman like I can hardly move came off tamoxifen & felt a bit better although not 100% because it stays in your system                Take care

  • Hi I feel exactly the same as you and I am also on tamoxifen, I feel this is actually worse than the treatment. I have been trying short walks and feel it's a struggle. My legs are sore and soles off my feet and my fingers. I feel some days are worse than others. I feel it definitely changes you. I also feel the mood swings are terrible too. I hope you are feeling better since your last post

  • Hi ladies, 

    I was diagnosed with hormone receptive breast cancer in March last year (2019), Had a lumpectomy, chemo and radiotherapy and started Tamoxifen in mid November. 

    I am now at the point of telling my oncologist that I can't take it anymore as the side effects are so debilitating. There's no let up from the hot flushes which make me feel sick and dizzy and the joint pain and tiredness are relentless. I'm still trying to process the cancer journey but the Tamoxifen is making things worse, I will be speaking to my oncologust on Monday and I'm going to suggest Clonodine. If he can't give me anything to help mitigate these awful supmtoms, I have to ditch the Tamoxifen for my sanity. 

    Take care all

  • Hi 

     

    I'm in the same position as you I was diagnosed January 2010 age 33 surgery chemo and radio and have been on tamoxifen ever since. This is my last year and the worst for side effects the pain in my legs is getting worse and hot flushes are terrible. Nothing I have tried reduces them when on long walks I take paracetamol and got myself a rechargeable fan for the flushes. I avoid certain materials as I just get hotter ! I am sticking it out until the very end January 2021 and that's the full ten years, and hard going it has been but I am still here and have had malignant melanoma when I was 21 also had mole removed 3 years ago with precancerous cells. I have also recently had thickened endometrial lining and polyps that I was none to pleased about! And a complex ovary ?! 
    All in all I can't wait to come off it and hope the flushes stop, aches go, weight goes down, and the *** doesn't come back. X

  • Dear Lindy-Lou,  I too have had such bad joint pains I had a big toe joint removed as the pain was so severe.  Unfortunately the plastic replacement brokw & the surgeon who removed it would not replace it again so I had what is called a "rubber" big toe which meant I had to learn to walk again.  Now, further down the line this removal has caused me to have bad episodes of sciatica, so bad sometimes, I have to use crutches.  Now more joint pain is occuring.  I do find practising yoga every day helps the most.  love Jan

  • I've been reading these posts with interest due to my own pain. I was trying to think of a life without joint/back/leg/feet pain and the most horrendous calf cramps. I recall this time was before tamoxifen. I am a very young at heart 62 year old, a bit overweight but normally have such a positive outlook but I've been struggling so much physically and mentally to the point I'm on antidepressants. One person on this blog had part of her toe removed and I wonder if this would have happened if tamoxifen hadn't of been prescribed. I accept we get aches and pains as we age but I feel sure my problems are caused by tamoxifen. I've debilitating pain in my thumb joints, I've tried tabs, creams, heat patches, capsicum patches, magnesium oil, steroid injections, and now wear gloves that wrap round my joint for support. Doesn't take pain away but feels supported. I've been taken tamoxifen since end 2015 and should take till end 2020 but thinking of ditching. Another thing to note, about 6 months ago I started bleeding vaginally and after many tests and hysteroscopy they found polyps and thickening inside my womb which they said was caused by tamoxifen!! By the way, if this happens to you, you MUST ask for sedation during any procedure as they are horrendous . Sorry to go on, this past 5 years I feel I've ages 15 years. I'm glad I'm not alone. Take care ladies. 

  • Hi 

    I gave been taking Tamoxifen for 3 years now. I've just turned 50 and feel 90 in the mornings. I walk each day for an hour , bath each night but struggle to get out of bed in the morning. Hot flushes have started again and sore feet. 

    Any ideas , I don't want to come off it but this is painful

     

    Hugs to you all going through the same xx

  • Hello. Thanks everyone for sharing your journey. Prior to Tamoxifen I was 49, active and dashed around 100mph, running up stairs, never sat down until the evenings, felt very healthy with zero aches and pains.  I started taking Tamoxifen November 2018. A friend of mine started at the same time and we waited for any side effect to hit... we both felt lucky that we seemed to have escaped. However 6 months later I started to notice a change in my muscles/joints and we had both experienced calf cramps/stiffness especially in the mornings and after sitting down. 

     

    After a a few more months, my back would not sort itself out, I tried yoga, new mattresses, kept moving, but the pain was affecting me so much I went reluctantly to the GP in the August. I explained to her that in addition to the chronic lower back ache I also had pains my knees, ankles, calf’s, fingers and thumbs. He answer was that we do get older and it was likely arthritis, gave me a leaflet on back exercises and told me to get on my bike to strengthen my thigh/leg muscles. She also wrote to my oncologist suggesting the tamoxifen but he wrote back and said no, side effects I’m experiencing wouldn’t be a side effect.

     

    I did the back exercises, I continued with low impact exercise & yoga. no improvement in my back. I then out of nowhere ended up with a rotary shoulder cuff injury in November 2019. Phoned GP and was given a website for shoulder exercises. By end December my shoulder was no better, inflammation and my thumb/wrist was now in a brace. No being able to use your right arm and shoulder for much was crap. I’d had enough. I got myself a private physio who gave me some proper shoulder exercises after shed actually examined me and made me walk up and down the pool to try and strengthen my now ridiculously weak legs and back. Still not convinced I was getting to the root of all this muscle weakness I did some private blood tests at home (Thriva). Results were that I had insufficient vitamin d.... one month later on a prescribed daily dose and back ache was gone and weakness in legs gone. Both of those symptoms are actually very typical of insufficient vit d... now that I’ve researched it more it would have sVe me a lot of pain and expense. So that’s the good bit. 

     

    The bad bit is that now I’ve got my back and muscle weakness sorted thr joint pain is getting worse and I’m very conscious of my hip, knees, clunking shoulders, big toe, small toe, both thumbs ache all the time, fingers etc.... I’m slower, much slower and compensate a lot when out walking depending on what’s hurting the most. I’ve had a test for RA which was negative so conclude that it’s all diminishing oestrogen related, peri menopausal, tamoxifen. I feel if I could calm the inflammation I’d feel so much better. I’m googling everything, some limitations due to some drugs/supplements affect how Tamoxifen works/risks (HRT, CBD oil...) feeling anxious about the future. It feels all to soon, too much at once, I was going to be one of those fit 50 year olds but feel very compromised now and anxious for my future and how much it will affect my lifestyle. Was very positive throughout my cancer diagnosis and treatment as I could see the light at the end, but this all feels very different. 

  • Hi.  Oh my goodness how I can relate to all of your story Shirley Valentine and thankyou for sharing your journey.  It makes me feel it’s not all in head.

     

    i was diagnosed with her2 positive cancer in 2017.  Prior to that a very active ,fit 57 year old.   I sailed through chemo, radio and herceptin and continued to be very active through treatment and straight after.    Then started Femera (AI). Which is first hormone therapy drug for post menopausal women.  After 2 and a half years I discontinued because of the debilitating effects it was having on me ( 10 weeks ago)Mostly hands/wrists and feet .  In April this year I couldn’t do anything with the pain from Tendinopathy.  I stopped Femera after discussing with oncologist and after a five week break am on tamoxifen.

    Visits to rheumatologists were frustrating to say the least and felt I really wasn’t been taken seriously and depression really set in. As you say you are limited what you can take with tamoxifen.  I tried CBD oil and thought this was going to be the life saver for me as it worked but found it couldn be used with tamoxifen.  Also limited use of anti depressants.  I tried escitalopram for 2 weeks and have to say it was the worse two weeks of my life.  Needless to say I stopped THese a few weeks ago and like you am googling for answers.   

    Everything says tamoxifen doesn’t cause joint/ muscle  problems but am pretty much feeling the same.   How can it not when it reduces oestrogen.

     

    I really cannot go on like this and want to stop hormone treatment.  I have in theory 2 years to go but just don’t think I can do it.  Just want to get back to being pain free and being myself again.
