I have been on hormones for two years, living full time for the last year, and this morning started having really bad testicle pain.  Anyone else experience this?

Can't say that I have.  Though, I was only on HRT for 13.5 months before I got SRS.

Soon after I started HRT I begane to have terrible eppisodes of testicular pains. Often it would last a few days and go away for a week or so then come back.
It got so bad that I was able to get my insurance to pay for an orchi.

I had cysts and deformities on the vas defrens (sp?) and testicals. I don't know if they were like that pre HRT or not.  I assume so.

Really insane pain (enough to make you want to vomit) could be a sign of testicular torsion.
That is an ER kind of thing.

I had a very unpleasant pain in my testicles 3 weeks after starting hrt. It was more of a dull throbbing type of a pain, but has passed now.

I had pain myself a few months after starting HRT. I started a thread about it on here in fact. It eventually went away, but it did last a few weeks.

I got some pain but it wasn't severe, more a dull ache for a while. If you get severe pain get it checked as Renate and Cynthialee point out.  Just because you don't want them doesn't mean they cannot get diseased and impact on your health.
