I had
breast cancer with lumpectomy in 1994
and then 35 radiation treatments. Fortunately, I did not require chemo. And, I chose not to take the tamoxifen. But, I experienced extreme muscle and joint pain after the radiation treatments. I have fibromyalgia with chronic pain and I also took vitamins, etc. The radiation treatments caused my fibromyalgia to become acute. I began taking 1000 units of Fish Oil twice daily and found that after a short time, my pain factor was much, much better.
