I have been having a dull ache/pain in my left side. Well inside the left side of my stomach. It's not where the port is or where the band is (at least I don't think). What could it be? It's not super painful, but it's uncomfortable.

Any advise is greatly appreciated!

Possibly gallbladder, but definitely needs a visit with a Dr.

You need to see your family physician. We're not doctors, and even if there is a doctor on these forums, they can't diagnose you via the internet.

I am fairly certain it is not your gallbladder, the gall bladder is on the right side.

I can tell you that I get this type of pain on my left side when I have eaten something too heavy. For example, I tried to eat some whole wheat bread and maybe I didn't chew as well as I should have, but I had that pain bothering me all night. It also good be gas. Try some gas-x.

It sounds like its in the area of your stomach and the first thing I thought of was gas or food not able to digest as well. But if gas-x or pepto don't help get to the doctor right away. A while back I had stomach pain and it turned into something bigger and not band related so please take care of yourself.

if there is pain or uncomfortable feelings or something is not right, always call the doctor

I too would say check with the doc, better safe than sorry
