This sounds like a very distressing symptom. The type of physician you could see for this problem would be a primary care physician
such as a family doctor
or, if its a particularly complicated problem then you may need to see a urologist
. What is causing your burning genitals depends largely on what part of you is burning and what brings it on. If you burn with urination then it could have a urinary tract infection. If you are burning on the outside of your genitals then it is possible you have some skin irritation from a rash or infection. Tinea cruris (also known as jock itch) can cause itching and burning in that area which can be transmitted in a non-sexual way. I suggest you schedule an appointment with your primary care physician. He or she can take a detailed history, perform a thorough physical exam and may be able to determine if you have something that would require treatment. You may require a couple lab tests while you are there including a urinalysis. Your doctor may decide to refer you to a urologist for further evaluation and treatment. Good luck, and I hope you feel better.
