Poked in testicles by sewing needle

I was sitting in a car and forgot I had a needle and spool of thread in my lap. It fell down at some point and when I left the car I felt it poke my testicles. It felt just like if I had been poked anywhere else; felt basically like a prick. I examined myself and only noticed a little bit of red skin and a tiny bit of blood on the left testicle (front side).

Should I seek medical attention?

Thanks!
