Having lumps/boil on penis. Previously doctor diagnosis it as folliculitis . Privious one solved with  topical cream. But these boils are recurrent for me. 5 in last 5 months. Tested blood sugar and its normal. Most of them resolved on its own and self care. But it's comming back on different place of the penis 2/3 weeks after resolving previous one. Now having one just 3 weeks after previous one resolved. Want proper treatment and mainly prevention plan. Because  this one may be solved with antibiotics but I don't want that it come back again.
