I just had my sleeve done on Monday, I have been working my way up to meeting 64oz of water,taking walks,slow sips and have broth 1-2 times a day. I have been havening horrible lower back pain and idk what's going on. Is this normal? Could it possible be my kidneys?

I would suggest you call your surgeons office and see if they can offer some insight

I had that with my sleeve too. I work from home and I had to move everything to the couch because I couldn't sit in the chair at my desk for more than five minutes. It took several weeks but it finally went away.

My back hurts too after I take a deep breath. The pain is in the kidney area. I believe is due to soreness from the gas they put in our abdomen so they can see what they're doing. It doesn't hurt to run it by your surgeon though.
