Dear doctor, i m facing this extremely annoying situation of sweating mainly on face and forehead area (having moderate alopecia on forehead and mid head region ) from years. (I noticed it past 4-5 years). it is worst during hot humid climate and when anxiety or in tension (like getting late or facing some problem. I thought that it was because of warm condition but i realize that i m the only guy in surrounding who is sweating such profusely even drops of sweats starts within few seconds. armpits and other body areas are not having such problems. I used to wet tissues after tissues when under direct sunlight. It just happens only to me among all my contacts and friends. Mentally and physically fit and healthy. I m a happy, cool and calm type of person. but this problem, most of the time throw me in embarrassing condition
