Has anyone post-surgery had pain develop in both knees? I am trying to decide if it is because I'm using my legs more (to get up, to sit down, etc) or if it's because I've lost so much muscle in a short amount of time. I'm 3 weeks postop and I've lost 35lbs since I started my preop diet on Sept 18. I'm getting in 56-80oz of fluids/day and most days i get my 60gms protein in. I'm 48 and feeling 90!

Well that could be one of two things.. either you are not moving as much as you normally did and they are getting stiff OR you are moving more than ever and they are adjusting...

It's hard to tell, this did not happen to me and quite the opposite did, as I dropped weight moving became easier and my knees bothered me less.

See the doc, they should be able to help diagnose you and you want to make sure that it's not something coincidental to the WLS.

My knees hurt for awhile post-op, probably from a combination of moving more and from the ligaments/muscles not being stretched so tightly since I was losing weight rapidly. I also lost my sense of balance completely and ran into walls a lot for about 6 months. It's worth it, though!

Thank you for the replies. I have been having issues with continued abdominal pain and now my knees hurt too. It is frustrating. I hope the coming weeks see these aches and pains resolve!

My right knee been bothering me lately so I went and bought a knee brace. It's getting better though. Funny that I have been out for 14 months and now my knee is acting out!

I am 29 and was sleeved on sept tenth. I was having terrible knee pain. It was really deep down in my knees. I was also experiencing mild joint pain elsewhere. Went in and talked with my doctor and after some blood work determined my vitamin d levels were very very low. They put me on a prescription vit D and I take one pill per week. The pain stopped almost immediately. Just thought I'd let you know;). Good luck!

It might be a good idea to call your doctor. This doesn't sound right to me. It wouldn't hurt. At 3 weeks out, I had no abdominal pain except in my left incision site periodically.
