For the past few weeks I've been noticing a dull pain on my left side. It's not there all the time and it's not unbearable, but it's just weird. Anyone else have this?

All the time. Sounds like your port to me. I really feel it in the morning.

I had SILS so my port is below my belly button...could that still cause the pain? Could it be the tubing maybe?

Totally. I actually have my port removed currently because of an infection I had... And I still have that pain. I asked my surgeon about it hoping there was nothing wrong with my band and he said my tubing is moving around in there and causing the pain. I definitely feel it in the morning. I'm 4 months post op and feel it every morning. How long ago was your surgery?
