Why does Pinching a Nerve Hurt?
Nerves have many functions, transmitting messages around the body, rather like a telephone system. They allow us to feel things that happen to us, such as things we touch or that touch us, hot and cold, and pain, and they cause our body to do things, eg making your leg muscles contract when you want to walk. When a nerve is squashed, it may malfunction, and we might feel pain, numbness, pins and needles, and we might find our limbs are weak or do not work in the way they should. The nerve may also get inflamed and irritated by chemicals from the disc’s nucleus, without surgery. Pressure on the sciatic nerve from a herniated disc usually causes sciatica. The problem is also termed a radiculopathy, meaning that a disc has protruded from its normal position in the vertebral column and is pinching the root (origin) of the sciatic nerve. The degree of pain is often “ridiculously” high as well. Less direct nerve pinching e.g. swelling around the nerve is usually a less severe dull ache. Howe
