Severe Shoulder Pain? It Could Be Brachial Neuritis

Brachial Neuritis (BN) is a neuropathic condition (otherwise known as Parsonage-Turner syndrome or neuralgic amyotrophy) that affects nerves in the chest, shoulders, arms, and hands. This condition causes pain and loss of functionality in the nerves that act as messengers between the brain/spinal cord and the rest of the body. These nerves that run along the spinal cord, neck, and shoulders are what medical experts call the brachial plexus.

BN typically leads to terrible pain in the shoulders. After this episode expires, movement limitation then follows the extreme pain. BN is a rare disorder with a very quick onset and usually is at its worst during the night time.

There are two main types of BN: idiopathic and inherited. Idiopathic means that the cause of the condition is largely unknown, while inherited BN is passed down amongst family members. The former is much more common than the latter. Usually, the condition is the result of the patient’s immune system attacking the body’s nerves. Presently, medical experts do not exactly know how the nerve damage occurs in either idiopathic or inherited BN, but great strides in research are always being made.

Causes of Brachial Neuritis

It is not uncommon for BN to be the result of some sort of injury or trauma. Some injuries from contact sports, such as football or hockey, cause temporary weakness in the shoulder, as well as numbness and pain. More serious injuries from major trauma, such as a car accident or a harsh fall, lead to the same symptoms although their manifestation is much more persistent.

As stated previously, BN has to main causes: the patient either inherits it or the condition is idiopathic. The former is nowhere near as common as the idiopathic manifestation of the condition. As the name suggests, with inherited BN the parents of the patient pass down the ailment to their child. Idiopathic forms of BN are instead just forms of the condition where the cause is unknown. This version of BN is much more common than the inherited form.

A lot of the patients who have a sudden onset of BN have a few things in common. For one, many of them may say that they have just gotten over some other illness, disease, or germ. Others may say that they have just recently undergone some sort of test or treatment. This includes things such as spinal taps, injections, or other tests that utilize dyes. In addition to these treatments, some patients have a sudden onset of BN after receiving radiation treatment or surgery.

Symptoms of Brachial Neuritis

The condition almost always starts off with some level of pain, ultimately leading into periods of muscle weakness and lost functionality. The severity and persistence of these symptoms will depend on which phase of the condition the patient is going through, as well as the specifics of their case. While symptoms vary from person to person, a general list is as follows:

  • Sudden onset of extreme shoulder pain (typically the right shoulder). Many patients describe this type of pain as an intense stabbing or burning.
  • Symptoms of pain exacerbate when the patient attempts to move the affected shoulder.
  • Only the most powerful painkillers have any effect on treating the pain, with it still remaining constant for long periods of time.
  • Many patients describe a loss of function or temporary paralysis in the shoulder muscles after a painful episode.
  • Loss of muscle mass in the affected shoulder (atrophy).
  • Multiple areas of numbness develop in different areas of the arm and/or shoulder.
  • Sometimes BN affects the diaphragmatic nerves, which may result in shortness of breath.

Again, these are just to name a few general symptoms of the condition. It will always depend on the severity of your case, as well as your individual chemical composition. For more information, you should always communicate thoroughly with your doctor and remember to always ask questions.

How Do Doctors Diagnose Brachial Neuritis?

A fair question–after all the most common of the two types of this condition is the idiopathic form (meaning unknown cause). Of course, knowing the cause of a condition and being able to identify that a patient has BN are two totally different things.

To begin, your doctor will ask you questions regarding the nature of your condition and will perform an examination to look for areas that cause pain. If your doctor suspects BN early on, they will almost immediately test your shoulder functionality and muscle strength. In many people, it will be apparent which shoulder to examine first, as the affected shoulder often sticks out more than normally. During this time, your doctor will likely test your reflexes for anything unusual.

Once your doctor has laid down some groundwork, he or she will likely order imaging tests such as MRIs, CT scans, or X-rays. In some cases, your doctor may order electrical tests (such as electromyography or nerve conduction study) that show if individual nerves are performing as they normally should. Additionally, if your doctor suspects any other underlying medical conditions, he or she may order blood tests to check for those as well.

Brachial Neuritis Treatments

Most often, doctors treat BN with a multifaceted approach involving medication and physical therapy. That being said, there are some instances where a doctor may feel it is necessary for the patient to have surgery. These cases, however, are few and far inbetween.

Conservative Treatment

To begin, your doctor will prescribe you with some form of pain medication. Pain is the most immediate symptom, so doctors often address this first before anything else. Once the pain situation is brought down to manageable levels, your doctor will then began treatment to eliminate paralysis of the arm and regain functionality. In order for this to happen, your doctor will most likely set you up on a rehabilitative physical therapy program that may last up to eight weeks. The length of this program, as well as the nature of the exercises, will entirely depend on the needs of your case. Don’t worry too much though, as your doctor will set you up with a physical therapist to make this process very manageable.

Unfortunately, sometimes conservative treatments simply are not enough to get the job done. In such instances, your doctor may put you on the path of surgery. Usually, this only happens after two years of consistent failure from more conservative methods. Of course, you may be able to truncate this time period if you opt in for surgery earlier. For this, however, you will need to have an extensive conversation with your doctor.

Surgical treatment for BN usually involves repairing nerves via grafts from normally functioning nerves elsewhere in the body. If successful, this procedure will return function to the muscles affected by BN. Of course, surgical treatments do not just begin and end with grafts. It is also possible to perform tendon transfers if your doctor deems it necessary to restore function.
