Am 16 days post op and told I can do light exercise. I went to the gym and did a 30 mins walk, but towards the end of my walk at under 2 mph I started getting pain on my lower left part of my stomach. I had to stop because it started to hurt. Have any of you experienced this? Made me kid of nervous.

I have.. almost like a ripping feeling.. not sure what it was but it did pass so i was happy.. i was so scared that i had torn my sleeve or something.. maybe is just a muscle?

I haven't been sleeved yet, but I had laparoscopic gall bladder surgery a couple of years ago and the incisions are fairly similar to what you had for a sleeve. While I was feeling much better and returned to work 6 days after that surgery, I had pain in my lower abs for about 3 months after. I would notice it when I walked anything over like 10-15 minutes, it was a sharp, aching pain. I'd even notice it when walking in the grocery store or anything. It took a while to completely go away... but in the first few months, there were times I had to stop what I was doing (for example, if I was in a store) and find somewhere to sit down, or lean all my weight on. I'm not a doc, so I dont know what it is exactly, but it sounds similar to that, and my surgeon then told me it was normal and to be careful not to push myself when I felt that way, or else risk a hernia.

Go slow, rest often, and if it's really intense, talk to your surgeon. Good luck!
