I started to have pain in the upper left abdominal quadrant last Tuesday. It started as just tender when touched, but as the the evening progressed it began to be stabbing, sharp pains. Then, as I was getting ready for bed, the pains began to get unbearable; it felt as if someone were stabbing me in that area (just beneath my left rib cage.). I looked in my old anatomy book and saw that it was pretty close to where my spleen would be located so I grew concerned and went into the ER. Tests were performed, while I writhed in agony; urinalysis, blood drawn, CAT scan with contrast dye of abdomen, chest X ray, EKG. The doctor suspected an ulcer but I have never had one and take GERD medication daily. She gave me a "GI cocktail, composed of antacid and a numbing agent. There was no relief, so next they gave me Morphine (which I really don't like because it feels like I am dying) and still the pain persisted. Finally towards dawn, they added 5 mg of Valium (which is way too much for me) and finally the pain started to relent. Just before being discharged, the doctor suspected shingles. I did recall having an episode of intense itching in that same spot about a month ago, and having to apply cortisone cream. The itching finally subsided, but then I started having flank pain and cloudy urine. No infection was discovered then, and nothing was found to have caused this pain either. Worse, I am still drugged four days later, and very weak. Any speculations on what this could have been? I feel that if it had been shingles I would have broken out in a rash which I didn't. I am very puzzled.
