Localized symptoms of pinched nerve in the thoracic spine may include pain or stiffness of the midback. A pinched nerve at this level may cause pain into the buttocks or over the abdomen. T12-L1 Pinched Nerve: The T12 spinal nerves are responsible for the abdominal muscles and the skin over the buttocks. A pinched nerve may cause pain in the back, chest, or abdomen. T7-T12 Pinched Nerve: The T7 through T11 spinal nerves are responsible for the intercostal muscles of the corresponding rib, skin on the thorax, and the abdominal muscles. A pinched nerve may cause pain in the back or chest at the corresponding rib. T2-T6 Pinched Nerve: The T2 through T6 spinal nerves are responsible for the intercostal muscles and skin on the thorax, corresponding to the rib that it is numbered. A pinched nerve may cause pain in the back or chest at the first rib, or pain in the ring and/or pinky fingers. T1-T2 Pinched Nerve: The T1 spinal nerve is responsible for the ring and pinky fingers and the area at the first rib. Symptoms of pinched nerves typically unilateral, or only occurring on one side of the body. These nerves supply sensation to the torso and motor strength to the intercostal and abdominal muscles. The nerves from the thoracic spine run directly above each rib. A pinched nerve at the thoracic levels may cause pain and/or numbness in the back, chest, abdomen, and/or the ring and pinky finger. The exception is with the first thoracic nerve, which is also responsible for the ring and pinky fingers. The spinal nerves from the thoracic spine are involved with the function of the chest and abdomen. Localized pain symptoms from a pinched nerve may include neck pain, neck stiffness, decreased range of motion in the neck, and headaches. A pinched nerve may cause a weakened grip with pain that radiates into the pinky side of the arm. Pain may radiate down the back of the arm and into the middle finger.Ĭ7-T1 Pinched Nerve: The C8 nerve root is responsible for flexion of the fingers, such as with making a fist. A pinched nerve may cause weakness at one or both muscle groups. The triceps straighten the elbow and the wrist flexors bend the wrist to bring the hand closer to the forearm. A pinched nerve may cause weakness at one or both muscles groups with pain that may radiate down the thumb side of the arm.Ĭ6-7 Pinched Nerve: The C7 nerve root is responsible for the triceps and flexors of the wrist. The bicep bends the elbow and the wrist extensors allow for pulling the wrist back to put the palm up. A pinched nerve at the C4-5 level would cause shoulder pain and possibly weakness of the deltoid muscle.Ĭ5-C6 Pinched Nerve: The C6 nerve root is responsible for the bicep and wrist extensor muscles. Other potentially affected muscles include the bicep, triceps, wrist, and hand muscles.Ĭ4-C5 Pinched Nerve: The C5 nerve root is responsible for the deltoid muscle which sits on top of the shoulder, outside of the upper arm. For example, weakness in the deltoid muscle while raising your arms from your sides could indicate a pinched nerve at the C4-5 level. Pain is experienced in the body part that the pinched nerve is involved in the function of. Symptoms usually manifest as a sharp shooting or throbbing pain, numbness, tingling, or decreased sensation. Typically, symptoms from a pinched nerve will only produce unilateral symptoms, symptoms that occur on one side of the body. Spinal nerves that exit in the cervical region are directly involved in the function of the shoulders, arms, and hands, meaning that pinched nerves in this region will create symptoms in those locations. Pinched nerves occur most frequently in the cervical and lumbar spine due to their range of motion, but more frequently affects the latter. This can depend on the location of the pinched nerve, amount of compression, and cause of the pinched nerve. The symptoms of pinched nerves range from nonexistent to severe and debilitating.
