Hello I share your concern. Burning sensation and pain in testis and penis might be related to certain infection, passing of concentrated urine, trauma or inflammation of the penis and scrotum. I would advise you for blood test like CBC, liver function test, blood sugar, VDRL test and an ultrasound or colour Doppler of the testis. In my opinion you should have lots of fluids which will help by flushing off the urogenital tract and clearing of some mild infection. Meanwhile apply anaesthetic ointment like lignocaine and take acetaminophen for pain. Hope I could answer your question, Please feel free to ask for follow up question with a scan copy of all your reports so that I will be able to tell you more accurately. Best wishes
