I'm 6 months post-op for gastric sleeve surgery, came out with bad stomach spasms and have had stomach pain ever since. My surgeon and nurses in the office tell me to give it more time. However, I've noticed the pain has changed to stabbing sensations even when not eating. I don't appear to have a fever but have cold chills at night, and I'm very tired all the time. Is this normal this far out after surgery? Others that I have spoken with that have had this surgery don't experience what I am.
