I was thinking this too. I have varicose veins in my legs and arms (not face or back though...) and I keep seeing a commercial on tv that asks "if you have muscle spasms, burning etc. then we can help you treat your varicose veins and be rid of this"...
I keep asking my doc for a referral but he says no way this is due to vascular stuff... I guess it makes sense in my case cus I don't have varicose veins in my ears and scalp
