Five years ago, had had dermatitis on my face and scalp over 5 years ago, went to the doctor, and the current rash, with the tiny bump look a lot like the dermatitis rash from 5 years ago. However worried it may be ringworm but don't see any rings, can this spread?
Not ringworm; seems like allergic dermatitis
Detailed Answer:
Hello. Thank you for writing to us
I have gone through your query and I hope to provide a solution to your problem.
This does'nt seem to be a fungal infection/ ring worm
After going through the details provided by you my first impression if that this is likely a contact dermatitis (either to ? poison oak Or ?hair color agents).. considering that it is acute and recent in onset.
-Did you recently use a hair color?
Contact dermatitis to poison oak can happen after indirect air borne contact on exposed skin, specially since it is present in your surroundings.
Allergy to hair coloring agents too can present with itching, redness and bumps on scalp.
There would be ear lobe involvement as well as involvement of skin adjacent to scalp hair line i.e behind the ear lobes, nape of neck.
I suggest you to apply a mid potent topical steroid e.g triamcinolone acetonide 0.1% cream, twice daily, for a few days.
Hydrocortisone is too mild to be effective. The anti-itch cream that you have been using would provide only partial relief.
You may continue with the oral antihistamine e.g either fexofenadine Or cetrizine for a few days.
