I have been sweating under my arms for years, but I haven’t had any kind of major medical problems. My doctor said this is just an issue with the heat in the summer months. Sometimes it does not hurt, sometimes it burns or feels like a burn when I put lotion on. It gets worse at night and during the day until very hot outside. What should I do?
What causes underarm sweat? If you are still perspiring after several hours there may be something wrong with your skin. Is there itching beneath your armpits? Do you experience burning or stinging when applying deodorant to these areas? There could be something either trapped in the pores (a chemical that’s released into your sweat) or a problem with how your pits react to certain products used over time (like anti-perspirants).
