It doesn't feel bad at 1st unless you worry about it. Then things could get miserable but nothing you can't handle. The worst pain I have had is the Rad seed implants and these things make you foget rads and chemo. You won't feel much except the needle jab from the chemo but not much else at 1st. Good luck and maybe you are one that won't have after affects when it's over. Some here have had no problems.
