Weird issue concerning epigastric tightness, tense and feel unwell (unhealthy). I had a CT with contrast (liquid and IV) about 4 weeks ago looking for Kidney stones, they found 1, 4mm. However shortly after the ct (next day) I developed diarrhea, I assumed from the liquid contrast. 4 days after I had severe stomach cramps, since then I have had bloating both lower and upper abs, and now this strange epigastric tightness, just below the sternum. It feels as though I am constantly tense there, cannot relax my muscles, I also get a mild burning sensation in the stomach too...lying down helps eases the pressure, and antacids dont seem to help that much if at all. I have suffered IBS in my early 30's, now mid 40's.
I am regular stool wise, normal colour and consistency...no apparent weight loss but people do say I look thinner.
