c shaped lump on the top of right testicle
so just over a week ago I found a sort of C shaped lump on the top of my right testicle. I've been in a pretty panicked mood ever since. What's really thrown me off about it though is that it seems to go soft and actually disappear for a while some times. Sometimes after it goes away, masturbation or sex will make it re-appear, and then after about 15 minutes of no action it will go soft again and I won't be able to locate it. This is driving me nuts guys and i'm pretty scared. It's hard but not TOO hard and it hasn't grown in size since last week. If you guys have ANY input that would be great. If I detect that it grows in size during this oncoming week I will be seeing a doctor, but until that, any help guys? Thanks in advance.
