I had a lot of pain during the last couple weeks of my radiation treatments and after while healing. So much so that I hardly slept the last couple weeks of treatment. I would also get mock heart attack pain in my chest and upper back (maybe even neck and shoulder -- hard to remember exactly now) for 4 hours at a time that usually hit around midnight. Awful and intense. When I first described it to the radiation oncologist he asked why I didn't go to the ER to check for a heart attack. I told him because I have pre-x neuro issues and was playing the odds that the radiation was inflaming my nerves. I do have a hereditary neuropathy that makes my nerves get damaged easily. The chest pain did go away after radiation ended, but not immediately.

Also, is the sharp pain in your breast where you had the tumor removed? I still get occasional sharp pains where the tumor was removed from my chest wall and pectoral muscle. The pains were frequent in the beginning. Still makes me jump when one hits. It's also still very tender to touch that spot after 3 years so I guess it always will be. My sides under my arms where the extra tissue landed after my double mastectomy 10 years ago is still painful to touch, but again probably due to my pre-x neuropathy. Hopefully your pain will clear up quickly if you didn't have nerve issues prior to treatment. Prayers for you.
