In October I had a pneumothorax on my left side. I ended up having 4 of them total on the same side before having a pleurodesis done. Sometime after the second time it happened I started getting this aching pain on my left side an inch or two below my left breast. It's not constant, but would happen pretty frequently. I had a chest CT before surgery which didn't show anything, but I've always been a little worried about it, and wondering if it could be pain in my diaphragm or something that happens because of a pneumothorax?
