My left lower abdomen has a bulge. Sitting is uncomfortable. I have discomfort and some pain in this area and my back. I've had to work laying back. If you see someone driving down the road with their left arm on the car ceiling, leaning to the right, that'me. This started differently - severe pain that would last a few seconds then repeat a 4-5 times. Pain to the touch in my lower left abdomen. Back pain. Bloodwork & ct scan then MRI & colonoscopy only showed areas of moderate inflammation. Woke from colonoscopy in tremendous pain-morphine & another x-ray showed no damage. Doc said there was a ton of spasming which is an indication of pain, but why? A visit with surgeon an another ct scan as I started feeling less symptomatic showed less colitis, inflammation, and only diverticulosis, no diverticulitis. But no real answers. No hernia. No abscess. They are putting me on Flagyl which I will start Monday (1st antibiotic in 8 yrs - very allergic so I'll wait.) It seems to be getting better on it's own - I can sit for longer more comfortably. But what the heck is it? And now when I lean left sometimes it feels like my rib is catching on something. Anyone have this with an actual diagnosis??
