I have all these issues and have an abdominal scan in two weeks. I’m freaking out. Already been through ultrasounds and a CT scan of my kidneys. Feels like there’s something under my rib. Reminds me of being pregnant and a baby’s foot in pushing into me. Sitting for me is the worst! The pressure is so bad. I feel it in my back and shoulder too. Sometimes (not as often and not a bad) it moves towards my right, but mainly all revolves around my left. My organs all look normal. Had stomach and colon scopes done too. UGH! I do have GERD and a hiatal hernia too. I’ll check back to see your results and post mine. Good luck!
Stevens-Johnson syndrome: A serious systemic (body-wide) allergic reaction with a characteristic rash involving the skin and mucous membranes, including the buccal mucosa (inside of the mouth), conjunctiva, and genital areas. Abbreviated SJS. The disease is due to a hypersensitive (allergic) reaction to one of a number of immunologic stimuli including drugs and infectious agents. Complications can include hepatitis, nephritis, gastrointestinal bleeding, pneumonia , arthritis , arthralgia, fever , and myalgia. The diagnosis of SJS is usually made when the characteristic rash appears 1 to 3 weeks after exposure to a known stimulus and it cannot be explained by another diagnosis. The treatment depends, in part, on the suspected precipitating cause. Also known as erythema multiforme major.
