MYSTERY
In the back I lie
Snuggle in between two hard rocks
I am actually made up of two parts
One hard like rubber
The other soft like jelly
I provide springy actions
For the two hard rocks
When pressurized, I protrude
And hit onto the little nerves
Giving rise to pain
What am I? 
Can you tell me what is the specific name for the pain?
