Hi so I'm 5'10 weigh 73 kg. I go to the gym 6 times a week and lift pretty heavy weight. 3 days ago I went out to a sushi place to eat. A day after that I had watery diarrhea, small amount pretty frequent in the morning but got better as the day progressed. That same night I went ton the gym and lifted really heavy weights, working out my back, i also worked Out my abs. It's been 2 days and I have this pain under my belly button. Its not the pain I usually feel after an abdominal workout. I don't see a bulge and I palpated the area and I dint feel a lump or anything irregular. I also started taking protein shakes 3 days ago which also exacerbated my diarrhea that day. I was wondering if the pain I am experiencing under my belly button is a hernia? It doesn't huts per se but when I flex my abs and lean forward it is tender right under the belly. I just want ti know if it's a hernia, if it's related to the diarrhea or strain from working out 6 days a week. Thanks
