From last two weeks I am having a pain in my left testis, may be caused due to an injury that happen while I was kick starting my bike initially there was no any pain or anything few days later it started paining when ever i touch while bathing the epidermic seem more prominent in the left one and pain goes up to the stomach some times it seem the nerves are paining, and some time i feel burn in urination may be coz of water that I didi nt had properly. I am worried
