It's been 17 days since having the lapband surgery and I've started walking a little 2.0mph for 20 min. I was ok for a few days but now when I walk or up on my feet doing something my lower left side of my stomach hurts like I've had a bunh of water and I've walked 100 miles lol.. You know that cramp feeling? Do you all think I'm starting too soon?

I get that feeling after I eat and when I lie down. I don't know what it is, but it's very uncomfortable.
