It sounds like an inflamed follicle. The lump you've been feeling under the skin is most likely inflammatory tissue. The recent "popping" may well be from your manipulating it. Best to leave it alone, so the body can reabsorb the inflammation, which it no doubt will. If it worsens, you can show it to a doctor.
Take care.

Forgot to mention the weekend that i noticed the red spot I had a fever of 102, sore throat, night chills/sweats and sore muscles.
