Hello dear
I understand your concern
Lump could be a infection of hair follicle, sebaceous cyst/block
sweat gland.
Physical examination help in the diagnosis.
As a treating doctor, I will give following advises:
Local application of antibiotic cream like Mupirocin: 2-3 times/day
Tablet ibuprufen three time a day
Apply warm pad compression
If there is pain warm compresses also help.
Wear pure cotton loose undergarments and keep the area dry.
It will disooves in the 1-2 week
Take healthy diet, green leafy vegetables and fresh fruits with mutivitamin to boost the immunity and faster healing.
Hope this may help you
Contact HCM for further health query
Best regards
Dr. Sagar
