Soreness in lower middle stomach 5 months post op

So I'm five months post sleeve surgery and for about two days now the lower part of my stomach has some pain. If i lean forward while sitting it hurts. If i hold my stomach in it hurts. I dont know what this is. It comes and goes. Have any of you experienced this, or something similar?? Any suggestions on what to do! The doctors office is closed for the holiday.

Gall bladders are supposed to be rather sensitive after WLS.

but that's all I know - if not had gallbladder trouble before or after *touch wood* so don't know the whys or wherefores

If the pain is severe, you should go to ER.  Otherwise, call your doc first thing in the morning.  It could be anything from your gall bladder, to a kidney stone, to a problem with your sleeve, etc.  Or even just constipation!
