Hi. Today when i woke up i feel a little pain on my left testicle. I touched my left testicle and i feel a lump and the lump is around a small grape sized. The day before i didnt have any lump on my testicle not even any pain or anything. It just formed over a couple of hours and now it is pretty big like a small grape. I touch it and it doesn't hurt and i squeeze it and it feels a little bit of pain, just a very little. It is not hard and not very soft ether to touch. i am only 13 and i feel so scared. Please help me thank you.
