Hi,
Welcome to the ehealthforum. I am glad to help you out. From the description of the symptoms, the possibility of folliculitis seems high. Folliculitis is probably the most common of all skin infections. Although usually trivial, it can produce extensive disease. It may be superficial or deep, and it causes the formation of a pustule or inflammatory nodule surrounding the hair. In the majority of the patients, it heals itself without any intervention and only washing with anti-septic soap is sufficient. However, local application of an anti-bacterial ointment can facilitate the faster recovery. Some patients who have extensive disease need oral antibiotics for the same. Please do consult a dermatologist.
I sincerely hope that helps. Take care.
