Side affects

just noticed a post I answered was 2011 So I did a new one. I have a few of the listed one with the addition of premature aging where the radiation fields were, All around my mouth I have wrinkles like a prune wasn't there before radiotherapy. The rest of my face stayed the same. Also when I stretch my neck slightly tilted back to look at a high shelf I lose my balanced. Sometimes things go black and I go dizzy. If I move suddenly I go weak for a second or two....low blood pressure. Apart from minor things I'm fine.
