These skin bumps. How would you describe them? Are they reddish in color, are they white?
Do they scale ?
Are they flat or raised?
Where are they located?
Differentials for this are fungal infections and psoriasis. Fungal infections present as red rash with redder borders. The color becomes lighter at the center. Some fine scaling may be noted. The rash is usually itchy. As for psoriaisis, the rash is usually whitish and have more scales. The scales may easily slough off and pinpoint bleeding on the surface may be noted.
Topical corticosteroids may help in both cases. However, I suggest that the diagnosis should be ascertained first. A microscopic examination of the skin scrapings in the area may be able to help exclude a fungal infection.
