Hi and welcome to HCM.
It sounds more like you ve pulled abdominal muscles so I dont think this is intraabdominal pathology. You should take some of the standard painkillers or voltaren
gel and wait 2-3 days to see is it gonna improve. If not then some stomach or gallbladder
issue shoull be considered. Try to eat easier food and avoid alcohol and smoking
.Also it is not recommended to eat 2 hours before and after exercise. Wish you good health.
