Tightness, soreness and swelling 6 months post op TT - is this normal?

5.5 months post op TT. Still A LOT of soreness & tightness. Cannot exercise much & even hurts if I have a long day at my desk. Main reason for the TT was diastasis repair that I think contributed to back issues. I am 5’4” & 125lbs so the procedure was mainly muscle repair. Has anyone encountered similar issue? And yes, I TT my Dr. He said this was not normal and nothing he could do. He is board certified, 5 star rating on this website and others I researched so RELLY disappointed & at a loss..
