Grissom,
I have head, neck and facial HH and believe me that is enough to affect your life. When its hot and I'm in a meeting, especially after walking to the meeting, my head and face can stream so that I'm constantly wiping my face and my hair can stick to my head. Everyone notices and thinks I'm nervous but I'm not. Then I get worse because of the sweat and it then affects my overall performance. Recently I had a major 'sweat' whilst at the barbers as she was cutting my hair. There was no where to hide and I had to stick it out as she cut my increasingly wet hair and damp forehead. Not a fun time for me or her.
I also have mild truncal and palmer HH but that doesn;'t cause me too many problems, it's just the face and head.
Not to underestimate your problems as hands, feet and armpits must be a nightmare when its bad. I simply think that each of us are dealing with the issues that affects us in different ways and we all probably think that our own case is the worst. I certainly think my facial HH is appalling.
Good luck to you and I hope you find the cure you need.
Regards, Bill
