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 

  • Hi Michelle

    Gosh, I feel I could have written your post - exactly the same.  I started on anastrozol but couldn't cope with the joint pain so was moved to tomoxifen. Joint pain is still there though not quite so debilitating but the hot flushes are getting to me so much.  Also, I read that weight gain is a problem and I really need to lose weight as I have developed a heart problem.   

    I think ill contact the Oncologist and see what she can suggest.  I just want some normality back.

  • I have been on tamoxifen for 6 years. I had aches and pains at the start until I found the Teva brand recommended by someone else and then never had any side affects. Sadly I can't get the brand anymore and my aches and pains are back with a vengeance with the different brand I now have, to the point I don't think I will carry on. Convincing your doctor it's the brand that's at fault is difficult but I've heard it so many times and we know our bodies. 

  • I thought it was just me! Fingers, wrists, hip, left foot!!! I get up out of a seat like an old old lady!!! I've been taking Tamoxifen for 8 months now to counter a recurrence of ovarian cancer (who knew?!) and because it has had the desired effect of calming everything down, I've kept my mouth shut about the side effects. But my darling husband now thinks it's time to talk. I'll mention it to my onc at next appointment and let you know what he thinks. Have a great day, everyone!

  • Kath1961i had a lumpectomy and 3 lympnods removers beginning of November and  i started taking tamoxifen in November I started with pains everywhere the pain black as to be the worst atm  I do get pains in my feet . Hands . Calf's but the back pain is something else I take tablets got. Vitamin d deficiency so I hoping the pain will subside 

  • Hi Michelle, I had same treatment and was also prescribed tamoxifen. It's really affecting me and I really am considering coming off it. Just wondering if you came off it and if you were given an alternative. I work with children so I'm bending down a lot and it really is a struggle.

    Hi Suziewong,

    Have a chat with your oncologist about alternatives and see what s/he says. There are a few alternatives, but all come with their own set of side-effects. I moved on to Letrozole from Tamoxifen, but found this harder on my joints. However, it was better for my emotional state.

    Please don't just stop, talk to your care team first. You could always phone up your breast care nurse to discuss this.

    Please keep in touch and let us know how you get on. We are always here for you.

    Kind regards,

  • Wow ladies, i too found this post after googling joint pain and tamoxifen. I was diagnosed with hormone receptive lobular bc in July 2019. Partial mastectomy and radiotherapy then started tamoxifen. I have to say I'm not brilliant at taking it daily - it's a bit of a mental battle! But have been on it now since Dec 2019 and have been told I need to take it for 10 years. Over the past 3-6 months i too have aches in my feet/ankles, the base of my feet, my left hand - at the base of my hand, under my little finger, my left knee has now also started aching. When I get up in the morning I walk like an old lady (I'm 50). Also struggle when getting up from sitting for a period of time. My dexa bone scan in Nov 2019 (before tamoxifen) showed I have osteopenia - the onset of osteoporosis, so have Adcal D3 tablets to take (not good at taking these either). I get horrendous cramps in my feet and toes and feel so tired all the time. I haven't been to a dr as feel Im coping but I am conscious that the aches are getting worse. To be honest - if my qualify of life really started to suffer I have no qualms about stopping my tamoxifen. But I'm not sure if these aches and pains are tamoxifen or the menopause - which I feel cheated that I can't take any HRT for (my friends are all raving at how amazing it has made them feel). Sorry for the moan but good to know I'm not just going mad and we all know how each of us feels.

  • Hi Lindy Lou and all fellow survivors 

    I had same as you back in September 2015 I'm into my 6th year on tamoxifen and main side effects are the hot flushes and worse joint pain all over!!! I don't sleep much due to tossing and turning and having to stretch in agony!

    I did have a break for a few months but was advised by my consultant to go back on it as my flushes were still much trouble. The joint pain is still not good from my shoulders to my feet all over!! I have my consultant calling me tomorrow for a review since going back on it so will ask what they could suggest I try. I'm also wondering how my bones are now effected and could I have arthritis? it's hard I know what to think as we are governed by the specialists aren't we. I have tried all the drugs like tamoxifen and meds to help with flushes but nothing has worked to date. Unfortunately like I always hear what works for one doesn't for someone else. I'm just so glad I'm still alive like millions of others including you, so good luck, speak to your experts who look after you and be kind to yourself. Take care xx

  • Hi

    I have found this thread so helpful. I had breast cancer in 2013 and have been on tamoxifen for 9 years. I have had no side effects until recently when I have had unbelievable joint pain. My GP said I had been through the menopause (I'm 45) but can't give me anything due to my cancer type. I've eventually six months later just been referred back to oncology.  He said I may not have been through the menopause - so very confusing and said it could be the tamoxifen. He said as it'sbeen 9 years I can come off it but obviously this worries me. I didn't know this was even a side effect. However reading these posts it could be the problem. I think I'm going to try coming of it for a few weeks, he gave me this option and see how I feel. He has also said I could have Anastrozole instead but it has other side effects. I just can't carry on in this much pain. Thanks for sll your helpful stories. 

  • Hi. I too am a survivor of bc (surgery 04/08/20 )which had also spread toy lymph nodes under my arm. It was also er and pr positive. I had a lumpocetomy ,chemo , radiation therapy and then put on examastin.   Like you all it was OK at the beginning then I started having the joint and muscle pain so much so that I even had to leave my nieces wedding as I could hardly walk for the pain in my left knee. I also had xrays done of my wrists as well as I had pain just below the thumbs. 

    Anyhow oncology doc gave me a 6 week break to see how it was, nothing changed was still having the pains .so he said he would start me on a new one. Tamoxifen. 

    Well. Here I am now  with both knees causing excruciating pain that I'm attending physio for them which the physio told me was also coming from my back and hips.   He did say that I had some damage to my knee caps and loss of muscle above them.  Even yesterday sister made a comment that my legs are skinny now considering I used to have fat legs. I might add I still have swollen ankles 24/7. 

    I don't know if I should ask if I can try another drug as this is the second one and it's caused the same pain. 

    Also at the moment I am undergoing tests to see why I have lost so much weight without trying. Which was  started by my chemo nurse noting that from my previous bone strengthener infusion I had lost 10kg. So she called my gp to organise tests which my gp questioned why as it should have been done by the oncology department as I am still in the first 5 years of diagnoses. 

     

     Sorry just everything is coming out as I type this reply.  Last night was a bad one. The cramps in my ankle and u]p my shin was unbearable each time I managed to fall asleep it woke me back up. 

     

    It's good to know I'm not just being a hypercondriac

     That it is real and that u all know exactly what I'm talking about. No-one who has not gone through it doesn't understand how bad it feels.   As people have said  , I feel old. I'm 51 but feel like 88
