Recently I started getting this weird numbness under my left breast just left of the upper center of my stomach. It gets worse after I eat. I had my gallbladder out a few years ago, so I know it's not that. It's not painful, it just this weird kind of pressure or vibration but it's really annoying. I don't have any vomiting or fever. Any ideas? I just started a new job and don't have insurance for 3 months so I'm hoping it's not s big deal thing.
