Hello. Welcome to ask the doctor.
I understand your concern.
I have seen the attached photograph also.
As per details, the most likely possibility for your symptoms is a condition called Folliculitis. It is bacterial infection of skin involving the hair follicle.
In such cases, I prefer to advise topical antibiotic cream like mupirocin 2 percent over the affected area.
If severe, oral antibiotics are also given like cloxacillin.
Visit your doctor so that he can do a physical examination and give you a prescription.
You can share my opinion with him.
I hope it helps.
