I imagine each and everyone of us can relate to this. I had a stiff neck and shoulders, headache (obviously brain cancer), I had a constant cough with a tight chest and out of breath (obviously lung cancer), convinced myself i was riddled from head to toe, all of it..... stress ! As soon as I had my lumpectomy and got my results, everything vanished. Health anxiety is terrible. I felt like a pressure cooker, ready to explode. Worst anxiety I've ever suffered in my life. The waiting game is torture, every step leads to another wait, but it all leads to the end game and hopefully getting cancer free. You absolutely do not sound ridiculous !! It's all such a shock, it happens to others, it doesn't happen to us. It's a nasty little wake up call and scares the bejesus out of us. Don't beat yourself up, you aren't doing crazy behaviour you're just having a normal reaction to a terrible, terrifying shock so be kind to yourself. Find something that works for you to help you get your mind of it, breathing techniques, listening to audio books (that was mine), meditation, movies, books ? Sending a virtual hug and wishing you short waiting times x

Thank you so much for your understanding and kind reply xx

I am so glad I came across your post. I have posted something similar so I know exactly what you are going through. I have another week to wait for the results of my biopsies, but the consultant seemed pretty convinced it was cancer. I had 2 biopsies done in my breast (2 lumps) and one in my lymph node which looked enlarged on the scan, so now I am convinced it has spread through my lymph nodes all through my body. Like you, since the biopsy day, I have had painful shoulders and neck (muscle pain) and a feeling like my chest is tight and I cant breath in properly. The sensible side of my brain is telling me it cant be lung cancer as why would the symptoms all show in the last week! Its much more likely that having your arms above your head when the biopsies were done and being very tense has made the muscles sore, but that doesnt stop your brain going into overdrive. I keep imagining them saying they can't do anything and I've only got 6 months, but I feel fit and healthy apart from a little tiredness (I have just been diagnosed with anemia). 

Its a horrible time and whilst I will be glad to get the results in one way, as its better than waiting for them, I am also dreading what they are going to say, so I dont think you are ridiculous at all, as I feel exactly the same.
