I had a pain in my upper left stomach, under the ric cage, that woke me in teh middle fo the night for two days. It's gone now but now my left arm is painfully numb for the last 12 hours and I have a mild headache for the last 6 hours. I have been taking low dose asprin (6) all day but it hasn't gone away. The only other symptom, that doesn;t seem related, is that I have to urinate often, every hour, but I'm not sure how that is related.
