Hi, Welcome to HCM.
It seems that you are having relapsing pyoderma
You know whenever there is relapsing pyoderma, there may be something wrong inside the body.I usually go for investigations to find out something wrong in my patients in my clinic. I recommond blood investigations...like Hb ,blood cell count, ESR
,Random blood sugar,HIV test
....etc .Pyoderma may be caused by streptococci,besides staphylococci. Negative test dose not rule out staphylococcal role. After thorough examination and investigations,go for perfect treatment. If there is some disease, treat it. Perfect antibiotics in proper dose and proper duration might improve the condition. And immunobusters may be taken to improve immunity, and thereby general health.
I hope you got my answer.
