A warm welcome witchywoman.
It is very frustrating when side effects pop up and sometimes they will and docs look at ya like it's all in your head. Very disheartening.
I agree with Carol, see what your rad Onc says and if you aren't happy go to your family doc. If you have been hurting that long it needs to be tended to. Sometimes we have to be pushy but it's our body.
Don't worry about repeating a question, ask anything that is on your mind, we are always here and let us know what you find out and good luck!
