Yes and I can actually feel it when I'm a little skinnier. It is really worth getting it checked out. Mine has caused my left lower lung to be slightly collapsed. This doesn't cause any problems though. What I do notice, is if I get sick with something and my white count is up. Then it gives me pain under the left rib cage. It is always a dull pain but if I get sick then it gets worse. You need to get into see your doc and get a CT. Probably difficult right now with COVID but I again would be persistent.
