Hi, Ive noticed a lump or mass under my testicles for the past few days. It doesnt usually hurt, but when I play or masturbate, I get a dull ache in the testicles. The lump doesnt feel very hardits more like a soft, worm-like structure. Sometimes, my scrotum feels heavy and hangs lower on one side. Im worried about what this could be. Should I be concerned?
