[|Human|] I have these very tiny black stinging specks on my scalp.They are about the size of black pepper.I ve tried everything I could think of to rid them.I thought maybe head lice,but no bugs.they re is also a coating on scalp that is clear in color that is tough.I ve used Rid,vinegar,vaseline,betadyne,peroxide,Dawn dishwashing liquid,rinse with chlorine bleach and warm water solution.They sting and when you comb hair they fall out and quit stinging.I ve cut my hair extremely short and that did seem to help some.What could this possibly be? Yelling for help! YYYY@YYYY
[|AI|]  Hi, your clinical presentation is quite unusual. Without proper diagnosis, treatment is quite difficult. How long duration that specks are there? Is there any other site of body have similar lesion?however, they sting, so suggest there is quite possibility that they are made of some infected and degraded material like infected black heads, sebaceous cyst etc. Final diagnosis can be made from microscopic examination of the lesion.
