A range of conditions can affect the nerves which may then lead to pain. The more common nerve conditions leading to forearm pain are associated with trauma or compression. The nerves of the arms originate from the cervical vertebra (neck vertebrae). If there is compression at this level then it can cause arm pain. However, compression can occur anywhere along the course of the nerve.
