I just went thru this!! They should NOT use bacitracin or neosporin around such a delicate area! The pain after surgery was bad enough with out this huge itchy buring rash now on top of it. I tried benadryl pills put switched to the cream. My Surgeon told me to do nothing..but my pharmacist who I have had for years and trust immensely told me to apply benadryl cream to rash..then every 4-6 hours gently wash off with damp warm wash cloth (I just wet a small section) being careful not to get insicion wet, pat dry then reapply. Its helped..it burns at first but after a few minutes the itching and pain is gone..after a few days of this the rash is about 50% healed and it covered my entire neck!
I cut down on the bacitracin to 3x daily to see if it will help. He wants me to used it until the stiches has all disolved. I still have some stiches that have not disolved yet. Once disolved then I can use mederma,aloe,or 100% cocoa butter. Its been almost 3 weeks since surgery. Hopfully soon it will disolve so I can just use 100% cocoa butter or mederma. I will still call him in the morning just incase.
I have a lot of itching, but I think mine is from the glue that was so lavishly applied (I neglected to mention to the surgeon that I react to acrylate-based adhesives). I suspect you are correct that it is the bacitracin ointment. I guess I would avoid putting something on that might make it worse. How long are you supposed to use the bacitracin? Can you stop using that or use it less often to see if that is what is causing the problem?
