Testiclepain, Weightgain, Kneepain(?)

I have gotten used to the slight pain in my left testicle, but at least 3 doctors have said that nothing serious is wrong, so I don't have to worry about cancer or any such things.

I have gained 5 kilos during the summer - they need to come off.

I have noticed that it's actually not just my testicle, but my knee, that hurts a bit. I've never heard of "knee-cancer", so except for it being this annoying, constant, minor pain, I guess it's not anything dangerous. Why didn't I ask the doctor when I went to see him today? Well, I forgot... Sometimes the pain is not noticable.
