Pain in the forearm can be sudden onset (acute) and include fractures of either the radius or ulna bones. Gradual onset of pain in the forearm can be caused by nerve impingements or from overuse of the wrist. Or from referred pain higher up the arm or shoulder.
Injury to the median nerve at the elbow may cause symptoms to appear in the forearm, wrist, and hand. Median nerve injuries are often caused by another acute injury which traps or tears the nerve, causing numbness in the forearm. Read more on the symptoms, causes, and treatment of this arm injury.
Forearm splints are similar to shin splints in the lower leg, although far less common. It comes on gradually, occurring in those who repetitively use their wrist, contracting the forearm muscles. The pain in the arm is normally dull and increases with movement, so resting from the activity is the simplest way to help this injury.
Volkmann's Contracture is a deformity of the arm, wrist, and fingers, caused by an injury to the arm such as a fracture or a crush injury. It causes a lack of blood flow to the forearm, which can lead to muscle problems if it is not dealt with quick enough. Raising the arm and releasing the pressure in the forearm (via surgery) are two main ways to help treat this injury.
The cubital tunnel is an area on the inner elbow through which the ulnar nerve passes. Cubital tunnel syndrome is caused by compression on the nerve and may also be known as ulnar nerve compression or hitting your 'funny bone'. There are various reasons why the nerve becomes compressed, inlcuding arthritis and repetitive bending of the arms.
Pronator teres syndrome is an entrapment of the median nerve, where it passes between the two parts of the pronator teres muscle in the arm causing pain, numbness and tingling in the forearm and hand. As the name indicates, pronating the hand (turning the hand with the palm facing down) can cause and exacerbate this arm injury.
Anterior Interosseous Syndrome is an entrapment neuropathy of the anterior interosseous nerve - a branch of the Median nerve. This nerve branches off from the median nerve, just above the inner elbow. In this condition, the nerve becomes compressed, causing symptoms like pain in the upper arm and difficulty moving the thumb, index finger and middle finger.
A broken forearm is usually a fracture to the radius bone, although maybe a fracture of the ulna, or even both. The radius is more frequently injured than the ulna because it is weight bearing. Immediate pain is the main symptom, with deformity sometimes being visible. Medical help is needed immediately if you have a suspected fracture.
An Ulna Fracture is a break in the Ulna bone, which is one of the two bones in the forearm. A fracture may occur from a sudden, direct trauma or impact, or a strong muscle contraction - known as an avulsion fracture. This arm injury will be very painful and medical advice should be sought to get the right treatment.
