I don't know if this is FMS-related or not. I have a very "full" feeling in my belly-area. I don't know if it's FMS causing the muscles to feel funny, or if it's GYN-related. I called my GYN dr. and she said I should have a urine test tomorrow. If that's normal, she may order an ultrasound. I've had this before but never found out what it was. I just had a GYN physical and everything was okay. Do any of you women get this funny feeling? Thanks.
