Hello, For the past week I've been getting right sided abdominal aches after having dinner. Does anyone know what that might be? I don't get it after breakfast or lunch. It's just a really bad ache -- no diarrhea, nausea, constipation, etc. I would the area affected is mid to lower right side abdomen, so I don't think it's the liver. I'm 30 male and I've read appendicitis is common for this group. But is appendicitis really just an ache after dinner? I've tried taking probiotics, apple cider vinegar, l-glutamine, milk thistle, aged garlic extract but it's not helping.
