<s>[INST] Hi, I am a 16 y/o male and I recently found a tiny bump just inside my scrotum on the surface of my left testicle. It feels similar to a scab. It does not really hurt or bother me as of now but if I mess with it I feel like I was hit in the groin. I m worried about what this is and am looking for information and advice. Thank you. [/INST] Howell come to ChatDoctorThis could be warts, just keep this under observation for any changes if ever happens, and if you found anything like this then this need to be examined clinically because skin lesion always demand the observation and this is the only way to diagnose the lesion, now for the lesion that you have just no need to worry about this, chances of vanish this bump could be enough, take care. </s>
