I feel a little pain once in a while on my left testicle.
Small aches that come and go once in a while are typically not a problem. You can mention it to your doctor the next time you see him, but I doubt this is something you need to schedule an appointment for.
When a pain is strong, makes you feel ill, or lasts for a long time, then you need to see your doctor about it.
