For years, I have been plagued with excessive sweating from the neck up. I can be sitting reading a book or washing dishes in the sink and the sweat just rolls down my head and drops onto my clothing. My hair becomes extremely wet at base of neck and it is extremely embarrassing when I am in public. This is a 24 hour a day, 7 day a week, 12 months of the year frustration. Can someone explain this to me and offer any answers to alleviating the condition?
