Pinched nerve is also termed nerve compression. This condition usually occurs when an internal or internal cause puts pressure on the nerve and affects its normal functioning. With this, the body supplied by that nerve gets painful and experiences a tingling sensation or numbness. The symptom that differentiates the condition from another type of pain is the presence of radiating pain. This happens because all the areas where the nerves supply is affected and get painful. This may be caused due to an injury or can even be due to age-related changes like bone spur formation or bone degeneration.
