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 of skin called Furunculosis.
It is bacterial infection of skin involving the hair follicle and surrounding areas.
The central part appears crusted.
In such cases, I prefer to advise topical antibiotic cream like mupirocin 2 percent over the affected area. For pain and information, anti inflammatory drugs like diclofenac is given.
I will advise you to visit your doctor so that he can examine you and give you prescription.
You can share my opinion with him.
I hope it helps.
