I'm still trying to navigate this site, I think it's rather difficult, have had to get help and still have some trouble. The places on your forearms, if your dermatologist knows you are getting treatment, I would think if she though necessary she would want to check one of the places. Continue going to see your doc and see what she has to say, also show them to oncologist.
I have leg pain but have had it for a long time before I started treatment, also back problems with lower back. Then after my surgery last April, during the course of several tests, a tumor showed up on my spine, it was malignant, so I had 10 or radiation treatments, then began chemo so they were going on at same time. Still doing Herceptin and Aridia, I get very tired after treatments now and try to rest all week-end so I can return to work on Mon.
Good luck to you, keep in touch and let me know how you are doing.
