Shoulder pain. On top of shoulder. 7 days sleeved. How long does gas pain last ?

Mine lasted about a week. It was awful. I switch between hot water bottle and bag of peas. Gas x strips also helped a little.

I had bad gas pains for about a week also and I used gas-x (chewable)when I got home. It worked really good

How did you know it wasn't a leak?

Use gas x strips they really helped. Mine lasted for almost two weeks.

With a leak you usually have severe stomach pain.
