because without this pump the inside of neuron will stay + and outside -( check that, I am not that sure)
and the neuron will not be able to function, as a result you will not feel any pain or even feel anything.

the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
potassium ions into the cell
The sodium-potassium pump (PDB entries 2zxe and 3b8e ) is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.

Na+ out of the cell and K+ into the cell

the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
The sodium-potassium pump is extremely important, especially in your nerve cells (neurons). The pump has 3 binding cites for sodium ions, and 2 binding cites for potassium ions. It uses these binding cites to pump sodium to the outside of a membrane and potassium to the inside. This an example of using ATP (energy) to go against the concentration gradient.
ATP provides the energy for the sodium potassium pump.
sodium-potassium pump
The sodium-potassium pump is a transmembrane protein in a cell membrane. It keeps large concentrations of sodium ions outside the cell, and potassium ions inside the cell. It does this by pumping the sodium ions out, and the potassium ions in.
The sodium/potassium pump, the sodium leak channel and the potassium leak channel.
3 sodium ions for 2 potassium ions.
In a sodium-potassium pump a carrier protein uses ATP in Active transport. The sodium ions are transported out of the cells and the potassium ions are transported into the cell.
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
