My testicles have been hit before 2 weeks now I don't feel pain but one testicle is red I also had been to urologist and he gave me medications 4 1 w.

My suggestion... Finish the antibiotics as prescribed by your Urologist and follow up as recommended. However, if you see that your testicle gets worse(more red, more swollen or more tender) make sure you see him/her as soon as possible.
Ultrasound? Did they perform an ultrasound to determine if there was any torsion ?..if not is should be done.
