Hi i am a 20 yo male and about a year or so ago i noticed a small almost vein like lump near my left testical. Thare was no pain with it and at times it almost seemed to go away. About a month ago i was in a truck roll over and was tossed out the window. it seemed to swell up and i noticed a small bruise on the bottom of my sac. since then it has seemed to grow slightly in size and cause me constant mild pain. it still feels some what vein like but there is a small marble size lump that is attached to the testical and is surrounded by the more veiny like matter. i have consulted a doctor and am awaiting ultrasound but i would just like your opinion on the matter due to the fact its driving me a bit insane. im constantly worrying about it and with the pain it is always on my mind. thanks for your time and i hope to hear back from you.
