There are a few reasons why arm pain occurs. Below are a few reasons explained.
Cervical Radiculopathy (Trapped Nerve)
This is the most common cause of arm pain. If you have a trapped nerve your body may send you warning signs such as pain, pins and needles or numbness. There are a number of reasons why it can become trapped with the most common being from a disc bulge, wear and tear or tight muscles in the neck. Symptoms can vary from mild to severe and can radiate either all way down the arm or just into the upper arm. The pain can be made worse by looking up and is usually worse at night. Conservative treatment can really help relieve symptoms. Treatments such as ice therapy, mobilisation, acupuncture, massage and nerve flossing exercises can help.
Thoracic Outlet Syndrome
As we are spending more and more time on our phones and at computers poor posture is becoming an increasing problem. This poor posture can cause the muscles in the front of your neck, known as the scalenes, to become tight and compress on the nerves and arteries that supply your arm. Pins and needles and numbness are normally felt in the arm when sleeping or sitting for a prolonged period. Symptoms should ease with movement. Manipulation, massage and stretches can usually resolve the issue but exercises are essential to correct posture otherwise the symptoms are likely to reoccur.
