Myositis As A Result Of Vaccine Injury – What To Do After A Myositis Diagnosis


Myositis is a term covering a group of diseases that involve inflammation, swelling, or “wasting” of muscle tissues. In some cases, this is a short-term issue brought on by vigorous exercise, electrolyte imbalance, or other acute causes. In other cases, however, myositis can be a long-term condition in which a person experiences chronic inflammation of the muscles along with other debilitating symptoms. Each type of myositis has its own unique characteristics, but chronic muscle inflammation is a common feature in all.

Symptoms of myositis can include:  

  • Muscle soreness and weakness
  • Difficulty going up and down stairs
  • Difficulty grasping and gripping objects
  • Falling unexpectedly
  • Weakness or soreness while getting out of chairs
  • Difficulty swallowing or breathing
  • Fatigue after long periods of walking or standing
  • Discomfort when trying to raise arms above head

Treatment of myositis can be complicated by the condition’s relative rarity compared to other conditions that can cause fatigue or muscle soreness. Many physicians will overlook myositis as a potential diagnosis simply because the symptoms overlap with so many other potential causes. Further, the symptoms can vary widely even among patients with the same type of myositis. Once diagnosed correctly, aggressive treatment including medication, immunosuppressants, and physical therapy are often the next steps for a myositis patient.

Potential Causes of Myositis

There are various causes and risk factors for myositis, some involving age, sex, or family history. Genetic predispositions combined with a “trigger” can lead to myositis symptoms in susceptible individuals. For inflammatory myopathies, myositis arises due to an autoimmune condition in which the body’s immune system is misdirected and attacks normal, healthy tissue. Inflammatory myositis occurs in about 50,000 to 75,000 Americans each year, with causes presumed to include infection, virus exposure, and vaccinations in certain cases.

Vaccine-induced myositis can occur in individuals of all age ranges and health conditions. In these situations, the typical muscle soreness around an injection site escalates into something more. Patients with myositis triggered by a vaccine may experience a gradual onset of weakness, muscle pain and cramps, and difficulty standing or walking. These symptoms may occur within days or weeks after the vaccine administration.

If a person experiences any myositis symptoms shortly after a vaccine, and no other potential causes can be established, they may have vaccine-induced myositis. If this is the case, legal recourse may be available through the U.S. Court of Federal Claims, which administers vaccine injury cases and the National Vaccine Injury Compensation Program (VICP).

Navigating this process can be difficult for most people to do on their own, due to the administrative steps and legal complexities involved. An experienced Philadelphia vaccine injury attorney with significant practice in the U.S. Court of Federal Claims can build your case and pursue it through the legal system on your behalf.
