I had meniscus repair left knee 3 weeks ago. developed a rash from the knee down only on surgical left knee. Rash was light red now it is dark red and won t seem to go away. Knee still swollen and having difficulty walking on that leg. I have a very noticeable limp. I have taken benedryl and used Hydrocortisone cream then changed to Nystatin cream not sure what else to do. My ortho said it probably is due to the stitches or ace bandage that i had, however the stitches and ace bandage was removed about 8 days ago.
