Sorry if this is the wrong place to ask, but just yesterday I noticed a strange pain in my left testicle when I woke up. It was nothing excruciating and didn't hurt that much; simply put it felt like I just slept on it in a bad position. The pain also went away within a few hours and was completely gone the next day. The odd thing is though, that afterwards my left testicle hung lower than the right, when before they were the same. Should I be concerned about this recent development?
