I am 64 and going through menopause. Sweats very frequent, quite overweight but never had body odor before. Now when I sweat and mop my face and neck with clean, cold washcloth it smells of ammonia. I am taking medications and supplements for fibro, chronic pain, anti-inflammatory meds, zantac, protonix, reglan for chronic stomach gastropareses, and well as colon problems. Through all this through the last 20+years I have never had a problem with odors. Help?
