Can a bulging disc pinch more than one nerve?

Okay do I have a bulging disc in my lumbar spine. Ite has pinched my sciatic nerve and a few weeks ago when the pain started I only had pain down the sciatic nerve on my right leg, but got the past week it's been going down the same line on my left leg and on the insides of my legs. Is it possible for a bulging disc to pinch more than one nerve?
