Hello all had a muscle flap and a Russell Tailor Nail put in my Tibia back in 1990 leg has done ok for the condition of leg. But now pain has been elevated since last year have seen many doctors. Have been told not to disturb muscle flap or Nail. Pain management spoke of putting a block in my back for pain. thinking of going to Mayo Clinic any input. I want to fix problem if possible don’t just want to mask pain..
