So I got my surgery on 15 July and I'm getting this strong pressure on My left side it comes and goes it feels like a Contraction?

I'm guessing that it's gas from surgery, but you should run it by your doctor.

The gas plays havoc, and it's the left side (shoulder) that's typically affected.

I second Mrsinto. While you are waiting to hear back, take some Gas-X and start walking. A heating pad to the affected shoulder helps too.

I'm sorry It's my lower left side stomach pressure comes and goes And I can feel my insides Crying it feels like it's squeezing me on my Lower left side rib

I had pain there the whole time I was banded. It felt like being repeatedly punched and twisted. My band was in the wrong place and was strangling my stomach. I'd check with your doctor soon to make sure everything's where it should be. Hope you feel better and it's nothing serious.

Yes sweetie, that is the gas at work. Just keep walking and taking gas X until it subsides in a few days. Congratulations on your surgery and good luck.

Def gas u will be okay. Walk walk walk!
