I'm so disappointed by the uncaring doctor my mother saw today. He is a pain management doctor and she is almost 75. Her pain is a constant 8 she can barely walk and he is like she can only take lyrica and tylenol all the while saying we can do injections and burn your nerves however she has had many injections already and none of them worked. She is low income and cant afford much of the treatment he wants to try but he refused to give her anything for her pain. However, he said quality of life is important and acknowledged that she had noone at this point but said there's nothing I'll do to help you except continue to use expensive treatments that do not work. Norco works for her but he refuses to give her anything. He was a horribly rude uncaring man.
