Bump on Right Testicle

Posted By Brian on February 26, 1999 at 00:46:53:







About six months ago, I noticed a small hard bump on the side of my right testicle, about the size and shape of a piece of rice.  It's on the testicle, because I tried to scrape it off with my fingernail and it wouldn't budge.  After looking at this page, I told my doctor and had an exam (I don't know if he even really felt it - it was so cold in that room my scrotum was really tight when I tried to point it out to him).  He told me to keep an eye on it but didn't think it was anything to worry about.  I have been examining it occassionally to see if it was still there and it is.
Yesterday, I stood up and felt a sharp poke down there that lasted only a couple of seconds.  Then last night I had a "rock in your shoe" feeling where that bump is, like it's scratching the inside of my scrotum and a tightness in that testicle.
I have been having some nagging lower back soreness for about three weeks and now I'm concerned that this may be a problem.  It's not the pea-sized lump I've read about and that makes me feel a little better, but I'd like to know what this could be if it's not cancer and if it could become cancerous.  It hasn't bothered me today.
Would a doctor or Doug Bank please respond?  Thanks.
