Welcome. Have you been checked by a doctor? Is it sweat? When did the problem start?
If I had your problem, I would use a cleansing enema (as opposed to a retention enema) as outlined below to cleanse and detoxify the colon.
Juice 3 lemons, add to 2 quarts of warm steam distilled water in an enema bag.
Lubricate the tip with aloe or vitamin E.
Insert liquid (take your time).
Lay on your left side and massage up your right side, across your tummy and down your left side to help loosen up the undesirables.
Hold the fluid in your body for 3 or 4 minutes, then release.
Not pleasant, but then neither is your problem. Hope this helps.
