I have itchy, sore, inflamed redness/raised bumps on either side of my nose and under the nostrils. They "crust over" with whitish flakes then start the cycle of redness, etc all over again. This has been going on for about 2 months. I have been researching this online and think it is seborrheic dermatitis. I have been using clotrimazole cream twice daily as suggested on the JUST ANSWER DERMATOLOGY site for 3 days now. My question is: what are the stages of healing of this problem? Now I have much more "crusting over" and it is very dry and more itchy than before beginning the use of the cream. By the description I've given do you think it is in the healing process? Thank you ahead of time for your opinion.
