I'm looking for an answer to my dilemma. I have an AV fistula or AVM in femoral artery/vein. Probably congenital. 2 weeks ago I had 3 stents placed, but unfortunately that didn't provide lasting results. I did get 3 days relief from severe pelvic pain (due to vasculature congestion?) and the hyperhidrosis stopped as well. The pain and hyperhidrosis have returned and I'm awaiting another surgery. Has anyone heard of an abnormal communication in large artery/vein causing excessive diaphoresis from head to ankles? No palm or feet sweats. I literally drip perspiration even in a cool room. Not an anxious person either. Is there any correlation? Not finding any refereed or peer reviewed results in my searches. TIA.
