Iodine/betadine does sting. It is used to prevent infection It is difficult to advise without seeing the wound. Are you being seen by a nurse or are you changing the dressing? The nurse in the surgery/doctors should see how the wound is healing and advise if you need to continue with iodine dressings or can use different ones
no barry - was not told - I had a lady nurse to dress my foot last Tuesday - there was a graze on my other knee I asked to put a wee dressing on it. She simply opened her jacket to tell me she was " podiatrist" and therefore not allowed to touch knees - which isn't that bad. I put one on myself.
The only thing I know about Iodine plasters is they were the only treatment to heal an Ulcer on my ankle a few years ago. I understood at the time they weren't going to use them in future..no idea why that was tho.
