I have had this for a long time now. I am 26 years old. Lately my left testical had been hurting to the point were it hurts to walk somtimes. I have heard you can loose it if it doesn't get enough blood. After i heard that i got nervise. After i went to the bathroom today i notice that my left testicale was shriveled like it was cold, but the right side was not. And i was not cold at all. What should i do.
