I'm in a lot of pain in my tummy below my belly button and to the sides. I've had pain like this for months and I'm undergoing investigation for endometriosis. However I exercised a few days ago and since then the pain is so bad it's hard to move about without flinching. It's tender to touch.
Is this just because I've pulled a muscle or has it made a problem worse? Is it worth going to the GP? I just feel silly if it's just a muscle strain
