I was wondering if anyone could help. I'm 26 and feeling great discomfort in my left testicle. When I was 21 I caught mumps and as a result it killed my right testicle. I had it removed but know I'm feeling kind of the same in the other. It's a constant dull ache and the slightest touch is so uncomfortable. If anyone can help me with this it wouldbe great. Thanks for talking the time to read this.
