<s>[INST] My friend (woman 72) has squeezing pain in right arm. They are not regular or weekly but every few month. She also recently had this in her leg behind the knee and was bulging in back of her knee. Had ultra sound and all was normal. I think she needs to see a cardiologist but she thinks they will say it s nothing unless it is on the left side. What kind of Dr. should she seek for this help. [/INST] Hi you will need consultation with a neurologist first and then if he feels than a consultation with a cardiologist.watch for functional pain in your friend. </s>
