It takes a full 6 months for the majority of healing and a full year for the rest. You're not even at the 3 month mark. You're struggling with a difficult post-op recovery, but it's far too soon to determine whether or not your wrap is failed. I know it's hard to trust, and wait for improvements.
I agree with Ashley's suggestion that you contact your surgeon and/or GI docs to get some feedback and understanding of what's going on with your recovery.
Until then, we're here to listen to your worries and support your recovery journey.
Words of wisdom by Eckhart Tolle:
"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
