What Causes Itching Between The Scrotum And Leg Area?

Where my scrotum meets my left thigh is constantly itching but feels like it is on the inside and even if I scratch there it feels like it doesn't really stop the itching. I also feel like my corpus cavernosum itches inside my scrotum as well. This has been getting progressively worse over the last year. I didn't think much of it at first as I attributed the itching between my leg and scrotum to being active and sweating, but it is now almost constant and has even prevented restful sleep. I have made an appointment with my doctor, but am unable to see him for another 2 weeks and this has me very worried at this point. Please advise if this is something that I should try to seek more immediate attention or if this is normal or what the heck is going on with me. THANK YOU!
