i had a c section with spinal block, they had to administer two doses of ephedra because I had difficulty breathing. Since that happened I often feel that same type of pressure in my chest like its difficult to breathe. If I take a really deep breath. I will normally burp or it will result in hiccups. The pressure often makes me feel lightheaded. I had my son 9 months ago and still have this problem. What is the cause? I never had this problem prior to this c-section. I did have a strong pain from the anesthesiologist inserting the tube down my back on the lower left side and she had to pull it out and push it back down. This was my second c-section the first I had general anesthia because it was an emergency and I was taking heparin due to an active blood clot; however I did not have this chest pain.
