Umm well maybe ask your girlfriend if you have one .I would start there and both get checked. If you haven't been with a girl for sure go to a doc fast
Hello,
This scab can be due to trauma after scratching, insect bite, scabies lesion or any other skin condition. Scabies is an infestation of the skin with the Sarcoptes scabiei mite. It is characterized by intense itching, usually at night and by small insect-type bites lesions on the skin. Diagnosis of scabies is made by scraping the skin and viewing the material under a microscope to see the characteristic mite or eggs.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
