Hi, last May i had a Spontaneous Pneumothorax and had to have a chest tube put in my side. Since then, i have been getting extremely sharp pains on my left side. The pain is right under my left breast and intensifies every time i breath in deeply or exhale too much. If i push on my rib cage, under my breast, the pain is not as severe, but as soon as i stop pushing, it comes back. When my lung collapsed, the started pushing on my heart, so im not sure if that would have anything to do with it. My doctor also said i have a slight SVT condidition. Im not sure what this chest pain is from, but its here almost everyday, and hurts really bad. What could this be? and how can i make it stop? Thanks!
