I get very tired when I walk, and I have abdominal pain too. Can anybody help me understand what might be going on?
First of all, we cannot diagnose you over the Internet. But beyond that, you haven't given near enough information anyway. My advice is to consult with your doctor if you are concerned about how you are feeling. There are just too many things that might be at work for the sort of vague symptoms you mention, both serious and not all serious. So allay your fears and get some help to start feeling better, OK?
