I have tiny raised red spots on my inner arms. Should I visit a doctor for this?

Hi,

Welcome to icliniq.com.

Is it one forearm or both? Is there any history of travel or stay in a new place like a hotel or camping? Is there any history of gardening, or playing outdoors?

Considering the history and after seeing the clinical picture (attachment removed to protect patient identity), I can provide the most probable causes for this rash.

1. Papular pityriasis rosea, an inflammatory condition that follows any kind of illness like flu, UTI (urinary tract infection), etc. It usually presents with red scaly spots that do not itch or hurt, starts on the trunk then extends to limbs and resolves on his own in six to eight weeks. Check for similar spots on the body as well.

2. Drug rash from the antibiotics that you took for UTI. May I know which antibiotic did you take?

3. Allergic contact dermatitis either to new cloth, sweater or new hand lotion. Do you recall using any new skin products or clothes in recent past?

4. Keratosis pilaris (KP) is one of the differential diagnosis if it is in both forearms (as in picture) and arms. KP is usually associated with eczema. Do you have any history eczema?

5. Have you been using any creams or ointment?

Please discuss the options with your GP or dermatologist and get the appropriate treatment. Take care.
