One month ago, while playing basket I felt a sharp pain in my testicle, but after that didn't worry about it because it didn't come back. Then I while performing self exam i found a lump under my testicle, but not connect it feels like a tube and it gets hard when i'm standing and soft when i'm laying down and i feel mild pain. This got me worried. I saw my doctor and he performed a physical exam and told me that i should not worry about it because its not on my testicle and he suspect that it is hydrocele or spermatocele. He also said that it looks like its swollen, but some part of it was healing. He suggested to wear scrotal support and put ice pack on it when it hurts.

I was relieved, but then when i looked it up online i saw some different things that may cause this problem and It made me worried again. So, the following week, I saw a different doctor and told him my situation and said what the first doctor told me. He again performed a physical exam and he said the same thing and told me if it gets bigger like a walnut to come back and see him, but he said i should not worry about it because men get this type of thing and he said he sees this type stuff all the time.

My main concern is that while doing research online, most site said that they have ultra sound, but my doctor never recommend that and just did a physical exam. Should i worry about it ? Should I see a third opinion?

thanks
