I am 21 years old and I am not sure that is it only a rash or Lyme disease rash. I have developed a small rash on my neck, I don’t remember being bit by anything and the spot doesn’t hurt it just itches but the area is red and bumpy and a little swollen with a small scab in the middle, I don’t feel anything like fever even. I need to know that is it a symptom of Lyme disease rash or not?
