I have had a pain for 3 nights after sleeping for about 3 hours I wake with severe stabbing pain whenever I breath in. I am forced to take short breaths. Pain will subside if i stand for some time. As soon as I sit laid back or lay down anytime the pain comes back and increases in intensity until I get up. I have been to the hospital and they have done an x-ray, EKG, CT scan to check for blood clots and found nothing. I am still in extreme pain at night and I am looking for any direction that will get a solution.
