Hello, I have been having severe pain in my abdomen for about 2 years. I had MRSA after a C-section three years ago, had my gallbladder removed two years ago and I can feel 10-12 masses in my abdomen on any given day. I recently had a ultrasound where the masses were unseen. I then had a catscan where the masses were still unseen. they are painful and hurt more with activity or a full stomach. are lipomas usually seen by ultrasound and catscan. really wanting some answers.
