Hi, About 10 days ago, I noticed my left testicle stopped hanging low, and has gotten very tight, and tender. For 3 days I had a pain on my left side in my lower abdominal. That pain has gone away now, though it comes back occasionally for an hour or so when my testicle is too high. It is uncomfortable, and even hurts a bit when I am walking. When I am laying down, or when I go to the bathroom (#2) the sack relaxes and goes back to hanging normally. Most of the time though, my left testicle is very close and tight, and does not even loosen much in a hot shower. Is this something that will pass as did the abdominal pain or could it be something more serious? Thank you
