Pig skin breast reconstruction

I had a pig skin reconstruction 2 years ago. I’m still in discomfort with it. Had my silcones replaced a month ago but the tightness of the harness inside is horrible. I’m restricted to what bras I wear. I’m so grateful I’m all clear now and don’t wanna sound ungrategul. Every day it itches and pulls and hurts. My doctor doesn’t seem to think there’s a problem but I’ve now asked to see a different opinion. Has any one else had this problem.
