Sweating on one half of the body

[vijay]

I am 27. I have been noticing for the past 10 months, that the left half of my body sweats more than my right half. Hyperhidrosis in left half. Basically, I sweat a lot when compared to others. It is not that my right half has stopped sweating, in bad weather it does sweat. Half-sided sweating is from the scalp till the toe, stops exactly at the midline of my body(left half is wet due to sweat and right half is dry). Other than that there is no other symptom. Muscle strength normal. All other physiological parameters as I know are normal. Please suggest me.
