I had a spinal fusion 7 weeks ago (although it feels longer) and have had worsening hypersensitivity since then. It started at the drain site and has spread to the point that it's down half my back and all the way over to the left and right side. My PT has me trying desensitization by rubbing the area and constantly touching it but it's not getting better. Anyone else have this. What has helped and how long did it take to go away? I am having a hard time brushing my hair and my clothing constantly bothers it. I need some help!
