question: Hi, may I answer your health queries right now ? Please type your query here... Hi... I just had an episode of sudden and severe pain in back between shoulder blades accompanied by squeezing pain along inside of rib cage. I thot I needed to throw up, got very hot and clamy, could not find a comfortable position. It felt like I had back labour. Lasted about 10-15 min. Now feel a bit chilled but other than that as if nothing happened.... what could have caused this?
