Rare Hyperhidrosis Sweating on Back of One Hand

Last week I finally saw a dermatologist who could help me. After 10 years or more suffering with pouring sweat from the back of my left hand, and googling the problem endlessly, I finally discovered the condition of excessive sweating was called Hyperhidrosis. When I was younger I saw a dermatologist that informed me he had never seen this, did not know what it was, thought I should tough it out, and sent me home with a prescription for Dry sol that burnt my hand and severely irritated my hand, not fixing the problem. Through my searches online I found two dermatologists, one through well renowned Dartmouth Hitchcock who has a branch in Manchester, NH, and one farther away who was willing to see me sooner. I scheduled both appointments and the first one was terrible. Dr. Campbell at Dover Skin Health did not spend more than five minutes with me, ignored my story, said less than ten words, and sent me home with a prescription for the same stuff that hadn't worked for me beforehand! It was a disaster, waste of a drive! After a three month wait I saw Dr. Willer through Dartmouth, and he was superb. He saw me 45 minutes late since my Lyme brain got me terribly lost, and spent at least another 45 minutes with me. He listened to my story, showed a diagram of the body's nerve pathways, described my condition and the concerns with certain treatments and their complications right now, and he even assured me we would figure it out once the Lyme clears up. There was nothing negative said about the diagnosis of Lyme Disease, and all was smooth. Dr. Willer had never seen a patient with this sever of a condition on the back of a hand, nor on the back of one hand. Usually patients suffer sweating on both sides of the body equally. So I guess I am one percent, and unable to receive surgery since the place of problem is nearly impossible to find. He suggested we get a neurological work up since usually problems on one side of the body are caused from a problem including a tumor in the brain or on the nerve somewhere. A tumor is unlikely after 10 years of dealing with this however, but still we should look into it. So when I see my new PCP for the first time I plan to discuss this with her.
