It's been over a month I am having indigestion, stomach issues, stomach ache and loose motions. Now I am having pain in the right side abdomen for no reason. I have been working a lot lately at office, yeah have been under mental stress as well pressure. So is that the cause? Or is it my liver? I used to drink alcohol but on moderate level previously but I have stopped. I just drink beer now and then. Pls help me, I am really confused!
