I felt this really bad pain in my left side. If you place the bottom of your palm on your left side right under your rib cage, the pain was in the area of where your fingers would be. When it occurred it hurt horrendously to the point I couldn't stand up. After a couple hours it started feeling a little better, and I could stand upward. Now left side feels like it is going to collapse and it is just very weak. Does anyone know what’s going on and if this is anything to be concerned about. Please help, it would be greatly appreciated.
