Hello, welcome to HCM. Hyperhidrosis
can be primary or genetically transmitted or secondary which is acquired due to a disorder of the thyroid or pituitary gland
, diabetes mellitus
, tumors, gout, menopause, certain drugs, or mercury poisoning. As you said you have already got yourself tested for thyroid levels and diabetes which are normal it could be a possibility that you could be having primary hyperhydrosis which is caused by an overactive sympathetic nerve. Nervousness
or excitement can exacerbate the situation for many sufferers. Other factors can play a role; certain foods and drinks, nicotine, caffeine, and smells can trigger a response. Aluminium chloride containing anti perspirants, botulinum toxin or anti cholinergic drugs can be very usefull for you. You must visit a dermatologist
who can prescribe you such drugs. Wish you good health.
