Agree that it is difficult to evaluate without an exam.
The infection as well as variety of topical treatments may have irritated the skin, leading to the fragility and sensitivity. The steroid cream may be helpful - however, it should not be used on a long-term basis. Hydrating creams can also help it heal.
If a skin infection is present, appropriate antibiotics would also help with the healing.
Another referral to a dermatologist can be considered. If the skin problems are refractory or continue, a biopsy can be considered for a more definitive diagnosis.
Followup with your personal physician is essential.
