Female, 43, 5'4", and appx 115lbs - all of a sudden last weekend, my sweat (mainly around my chest & breast area) began to smell very strongly like potassium (reminded me of a potassium drip you would receive if in the hospital) - I've also noticed over the past couple of months a few brownish color "patches" on my skin around my neck and upper chest area. Could these be related???
