 All right. So let me ask you this. Can someone tell if they have a disc herniation? Like, what does that feel like? Is it, I just got in an accident and now I have a disc herniation or I stood up or I got up out of bed in the morning and I had pain and that's a disc herniation. How do you know? That is really funny because you just mentioned two of the most common causes, okay, of disc herniation. So the short answer is yes, you can from those two specific instances. Okay.
