My experience was also not painful at all. I had rad and chemo. The techs at rad let me bring in my own music and played it for me at every session. I left it there for each visit. I wasn't too fatigued and I felt better than I looked which I didn't realize until I saw pictures of myself! I really looked sickly! After the 2nd chemo it did me in! I needed help walking and used a wheelchair to get to my rad tx at the hospital. But you will bounce back quickly from all of it no matter what side effects you experience. It's really great to have support during all of this, as much as you can get! You'll do just fine!
