I was feeling some swelling between my legs 2 3 days back I didn't paid any attention but a day before yesterday a mild pain started there and when I checked it it has swallowed around in 1 inch of area and upper thin layer of skin of this big cyst kinda thing has rubbed off and its been paining a lot what I am thinking it is a case of unattended boils or maybe a fungal infection. What should be done now is it home treatable or any prescribed medicine?
