HelloLooking at your description it seems to be a treatable condition and I will definitely help you in the best possible way if you can upload a photographs see patients with similar complaints in my clinic and after physical examination I would advise then for battery of tests like blood for hemoglobin, CBC, Liver function test, blood sugar and serological tests for STDs if suspected or a color Doppler of testis In my opinion you should wash bit properly with antiseptic solution and keep it clean and moisten manipulate or try to rupture it Hope this answers your question please feel free to ask for follow up I will be happy to help you Best wishes
