What can I do for sweating in groin/inner buttocks area. I believe its causing reoccurring boils. I am female don't wear underwear. Should I try botox?

Wear underwear is my. First recommendation since the cotton absorb the sweet, the second option is botox.
Zeasorb. Botox is fda approved for treating excessive sweating involving the underarms. For the groin area, using a powder such as zeasorb powder can help minimize this issue. If recurrent boils are an issue, using antibacterial soap such as hibiclens may help. In addition, a course of oral antibiotics and use of Bactroban (mupirocin) Ointment to decolonize the nostrils and fingernails may help. See a dermatologist.
