It could be an infection. In this case I would try using bactroban until it clears.
Perhaps it's granulation tissue? If so, the ENT might want to see it.
My docs let me email photos of the rash or redness in question. It might give them an idea of what you can start using. Rather than having to drive far.
The scar tissue can look red and inflamed. I wonder if that's what you're seeing...?
Good luck. Keep us posted.
