I don’t think you should of taken Charcoal pills without the doctors permission. Sounds like gas build up to me. Walk as often as possible and take gasX if permitted.
I had Revision Surgery on the 16th of June. I went from sleeve to bypass. I’m doing really well today. I did have gas in my shoulder, that was new for me. Get up and walk and take gasX if permitted. My stomach seem very swollen, like the whole thing. I feel very hungry at times, but I get busy and don’t get my fluid in, I’m fine after that. Your brain doesn’t catch up with your new stomach for a bit.
