There is no doubt that a pinched nerve can be extremely painful and troublesome. A nerve can get pinched when too much pressure is placed upon it by surrounding tissues. Nerves can be pinched or irritated by nearby bones, muscles, tendons, and cartilage, disrupting the nerve’s ability to function. In general, nerves perform one of two functions: they carry signals about movement (motor nerve) or sensation (sensory nerves). Depending on the characteristics of the impacted nerve, a person may experience pain, numbness, tingling, and weakness.
