If your work tasks caused your condition, you should modify your work site or your duties. Repeated use of the wrist in twisting motions (such as using a screwdriver) also make the problem worse. You need to avoid repetitive activities that require your wrist to be repeatedly bent backwards. The most important part of your treatment is to avoid the activity that caused the problem in the first place. Getting your symptoms under control and helping you regain the use of your elbow can be a challenge. Treating radial tunnel syndrome can be frustrating, for you and your health care providers. Once your diagnostic examination is complete, Innova Physio & Sports Rehab has treatment options that will help speed your recovery, so that you can more quickly return to your active lifestyle. Some patients may be referred to a doctor for further diagnosis. We will examine your neck as well as your arm, since radial tunnel symptoms may result from nerve pressure in either or both locations.Pinpointing the source of the pain will be most helpful in determining whether you have radial tunnel syndrome or tennis elbow. But it is important that we know exactly where and when you have pain. Our physiotherapist will then do a physical examination to look for the most painful spot. You will be asked questions about your pain, your activities, and any past injuries to your elbow. When your first visit Innova Physio & Sports Rehab, our physiotherapist will take a detailed medical history. Tests don't always help tell the two conditions apart. Many cases are initially diagnosed as tennis elbow. The diagnosis of radial tunnel syndrome can be difficult. Skin sensation is not changed because the sensory portion of the radial nerve branches off above the elbow and does not enter the radial tunnel. It can even lead to wrist drop, meaning the back of the hand can't be cocked up. Nerve pressure inside the radial tunnel leads to weakness in the muscles on the back of the forearm and wrist, making it difficult to steady the wrist when grasping and lifting. Radial tunnel syndrome may also cause a more achy type of pain or fatigue in the muscles of the forearm. In radial tunnel syndrome, the pain is centered about two inches further down the arm, over the spot where the radial nerve goes under the supinator muscle. In tennis elbow, the pain starts where the tendon attaches to the lateral epicondyle. One difference between radial tunnel syndrome and tennis elbow is the exact location of the pain.

The pain gets worse when you bend your wrist backward, turn your palm upward, or hold something with a stiff wrist or straightened elbow. As in tennis elbow, pain from radial tunnel syndrome often starts near the lateral epicondyle. The symptoms of radial tunnel syndrome are very similar to the symptoms of tennis elbow. The symptoms of radial tunnel syndrome are tenderness and pain on the outside of the elbow. What does radial tunnel syndrome feel like?

This is the motion of using a screwdriver to tighten a screw. The supinator muscle lets you twist your right hand clockwise. Passing through the radial tunnel, the radial nerve runs below the supinator muscle. On the lateral part of the elbow, the radial nerve enters a tunnel formed by muscles and bone. It then spirals outward and crosses the outside (the lateral part) of the elbow before it winds its way down the forearm and hand. The nerve passes down the back of the upper arm. The nerve roots join together to form three main nerves that travel down the arm to the hand. These openings are called neural foramina. The nerve roots exit through small openings between the vertebrae. The radial nerve starts at the side of the neck, where the individual nerve roots leave the spine.
