I have suffered from this skin condition for more than five years. It starts out like an inflamed pimple but there is a core that is hard and creamy like a grain of rice. It will get very fevered and inflamed and break open causing a sore, the sore will continue to drain puss and blood for several weaks getting larger as it progresses. I feel like I am a leaper or something. As I take a bath or shower the scabs come loose they have attached this grain like core and after the core comes out the sore heals up leaving a scar tissue. If the grain doesn't come out it may heal up but it soon re-infects and starts the whole process over again. This condition is primarily on my arms, & sholders however I have had it on my legs on occasion. Several dr's have looked at this condition but has done no testing, or have they made any suggestions as to what it is or could be. Is there a concern for skin cancer or does this sound familiar to anyone, if so what is it? How do you get rid of it? I have tried different antibotic creams, lotions, soaps, cleansers, nothing seams to help...
