What Is A Trapped Nerve?
Nerve tissue is one of the most sensitive tissues in the body. When nerves get irritated by surrounding tissues like joints, muscles or discs, the nerve being irritated can become painful causing referred pain and is often called a “trapped nerve” or a “pinched nerve”. Often the nerve is not “actually” pinched nor trapped- these simply common ways people understand the situation. When nerves gets irritated mechanically- a bio-chemical response around the nerve can create a very painful, noxious, burning sensation along the nerve and surrounding the nerve.
Where Can Nerves Get Pinched?
Nerves most commonly get irritated / pinched in the spine- usually around the neck, and the lower back (the upper back too- but this is less common).
Other common places for pinched / irritated nerves are at the elbow (ulna nerve neuritis), the wrist (carpal tunnel syndrome), the shin (compartment syndrome) and foot (morton’s neuroma), but there are many other places where nerves get trapped.
“Sciatica” is an example of nerve irritation in the lower back which causes pain to run down or shoot down the leg.
Sciatica usually only causes pain going down one side of the body and may or may not radiate below the knee. Sciatica can present with back pain, but on occasion can simply be pain or pins and needles in the leg. Symptoms can be experienced into the buttock and back of the thigh, into the knee and calf or even as far down as the foot.
How Do I Know If I Have A Pinched Nerve?
What Are The Symptoms Of A Trapped Nerve?
- Referred pain / tingling / numbness / change of sensation along the nerve distribution (in the leg or arm for example).
- Weakness in muscles that are supplied by the trapped nerve.
- Often a radiating / shooting / referred pain- on the side of the nerve irritation.
- Along with radiating / referred pain- there is usually pain at the site of the nerve irritation (eg. pain in the neck – with the referred pain down the arm).
- Usually certain movements or activities will aggravate the symptoms- which may indicate a mechanical type problem.
- Usually certain movements help provide relief- another indication that the problem may be mechanical.
