the only way you are going to find a definitive answer as to the nature of this skin lesion. and get an effective treatment is to physically see a medical professional either your primary care medical provider or a dermatologist. it is not possible for me or any medical professional to make this important call blindly over the internet without the privilege of seeing this area first-hand and having a more detailed medical history. if this condition has been going on for years i think it is time that you see a medical professional so you can be properly diagnosed and treated.
i have had this reoccurring "cyst" but i'm not really sure if it's a cyst. what is this and should i be worried? . it's been coming and going for years but i don't know why. i am overweight so i thought perhaps it was the skin rubbing and creating it but it's always on the left side of my underbelly and its random when it happens. it's usually filled with some puss and blood and takes a couple of days to close and go away. i clean myself daily and dry myself properly so it can't be that the area is infected. i just don't know why this cyst or whatever this bubble pocket thing is. i need answers.
