Question
I seem to get clusters of itchy bumps on my skin especially if I have a wound , scratch, pimple etc. I do have a habit of picking on blemishes on my skin (im a nervous guy :0)) but these dont go away. The example I attached had been a scratch, now its this itchy raised cluster. I have another few areas that are similar. Any suggestions? Ive been trying moisterizer with 1% cortisone, tried loratadine 10mg so i wouldnt get too sleepy but nothing seems to get it to go away. Any ideas?

Brief Answer:
Lichen planus

Detailed Answer:
Hi.

Thanks. After reviewing your history and after having a look at the picture, I would keep a possibility of Lichen Planus. Lchen planus presents as itchy, dry, papules and plaques, which are reddish to purplish in color. The itching is intense. They resolve with post-inflammatory hyperpigmentation.

Cortisone is very mild and won't help at all.

I would suggest a course of an oral steroid e.g prednisolone in a dose of 1 mg/kg/day for 2-4 weeks.

Topically you may use a potent topical steroid e.g either clobetasol or halobetasol, twice daily. These are prescription drugs and I would suggest you to see a dermatologist before trying them.

An OTC oral antihistamine e.g cetrizine 10 mg once daily would provide you symptomatic relief from itching.

Brief Answer:
Koebnerization

Detailed Answer:
Hi.

This is known as koebnerization, appearance of lesions in a linear fashion along lines of trauma/the scratches. This is classical of Lichen Planus and this picture further substantiates the diagnosis of lichen planus.
