A few days ago I had a sharp pain that started in my right shoulder blade that went up my neck to my head. Shortly after that, I had a sharp pain in my chest followed by shortness of breath. Ever since then, my chest has felt tight and I have had some discomfort in my right shoulder area, along with the shortness of breath. Since that has happened I have also noticed some pain under the left side of my ribs as well and a sharp pain in my left armpit. 8 weeks ago I had a c-section and before then I had been on bed rest for a few weeks. I went to the ER and they did an X-ray on my chest and an EKG and said everything looked fine and just told me that the tissue connecting my breast bone and ribs was inflamed. I just don't feel like that is right and I don't want to make another trip to the ER if this is nothing serious.
