Hitting a nerve while injecting would cause severe problems, including excruciating pain, paraesthesia, and possibly local paralysis.
depending on which nerve is damaged almost anything could happen
Hitting a nerve while drawing blood can cause nerve damage to the patient. This is very serious and can result in a permanent disability.

What happen to brain if brain nerve break
Very easily. Don't 'shoot' drugs.
Hitting the sciatic nerve when giving an injection in the buttocks can lead to permanent pain radiating from the buttock on that side down the back of the thigh. Sciatica pain can be debilitating! It can lead to problems and pain with just taking a few steps.
Vagal escape occurs when the parasympathetic nervous system, specifically the vagus nerve, fails to regulate the heart rate and the heart muscle is instead stimulated by other mechanisms. This can happen in situations where there is a prolonged increase in sympathetic nerve activity or when there is a dysfunction in the parasympathetic nervous system.
There are 2 different things that could be happening if your son is feeling pins and needles after hitting his shoulder. He could have a dislocated shoulder or he may have a pinched nerve in his shoulder or neck.
There would be no alcoholics in the world.
If you didn't have nerve cells, you could bleed out quickly. One example is if there's a needle on the ground and you accidentally stepped on it, the nerve cells will transfer the pain to your brain, then you would feel it and you would take care of the damage. If you didn't have them, you wouldn't feel the pain then you'll bleed out. You don't want that to happen. That's why you have nerve cells!
Potential problems for our nerve cells are that, if you happen to have alot of nerve cells that die you could lose feeling in your chest. You could suffer a heart attack. Another problem for neurons is that their axons, which can be quite long, are not good electrical conductors. Although neurons and wires are both capable of passively conducting electricity, the electrical properties of neurons compare poorly to even the most ordinary wire.
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.
