Bro,are you still alive?Just asking because i have the same thing on me
Hello,
It looks like an insect bite. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. If there is any itching antihistaminics like Benadryl or Claritin can be taken.
If the symptoms persist then get it evaluated from a dermatologist.
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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Also, the scratch was not hard enough to rupture any vessels, I had only just scratched at the bump before I noticed the tiny red specs...
