This might sound a little strange; but, rather than my stomach itching like it usually has when my skin is stretching, it's been "stinging" off and on. I've been keeping my clothes off my stomach as much as I can because I find that just irritates it even more. It doesn't look red or rashy or anything. Does anyone know what it could be? I haven't changed my laundry detergent (plus, it's just happening to the skin on my stomach).
