Myopathy: Early Signs of a Muscle Disorder and Next Steps

Maybe you grip the railing a little harder on the stairs now, or you push off the armrests to get out of a chair. Lifting a bag into the overhead bin feels heavier than it should. Changes like these are easy to blame on age or a busy week, but steady weakness in the hips, thighs, or shoulders can point to a problem in the muscles themselves.

Trouble rising from a chair, climbing stairs, or raising your arms are common signs of myopathy, and a muscle biopsy is usually needed for a definitive diagnosis. Read on to learn what causes myopathy and how to find the best doctor for myopathies in Las Vegas for the most advanced treatment.

Understanding Myopathy: A Condition That Affects Skeletal Muscle Fibers and Leads to Muscle Weakness

Myopathy is a broad term for conditions that damage muscle fibers and keep them from contracting with normal strength. Some types run in families, and others develop later in life from inflammation, medication, or hormone changes. Other neuromuscular conditions can look similar at first. Neuropathy affects the nerves that carry signals to your muscles, and myasthenia gravis affects the junction where nerve meets muscle. 

What are the Easiest Signs of Muscle Disorders?

Myopathy usually weakens the large muscles closest to the center of the body first. Signs to watch for include:

• Trouble climbing stairs or getting up from a low seat
• Difficulty lifting your arms to brush your hair or reach a shelf
• A waddling walk or frequent falls
• Muscle cramps, stiffness, or aching
• Tiring quickly during exercise
• Trouble swallowing
• A purple or red rash on the eyelids or knuckles
• Dark, tea-colored urine after exercise

It is important to seek care right away if weakness spreads over hours to days or if you have trouble breathing or swallowing.

What Are the Most Common Causes of Myopathy?

Pinpointing the cause of your myopathy helps determine the right treatment. The main groups of myopathy include:

How to Prepare for a Muscle Weakness Evaluation That Tests for Myopathy

Preparing for your muscle weakness testing can help your neurologist spot patterns faster and help you feel more confident in your results. Before your visit, write down:

• When you first noticed the weakness and whether it is getting worse
• Everyday tasks that have become harder
• Every medication and supplement you take, including start dates
• Any family members with muscle problems
• Recent illnesses, rashes, or changes in weight

It is also important to avoid hard workouts for a few days before blood work, since intense exercise can raise muscle enzyme levels.

How Do Doctors Diagnose Myopathy?

For an accurate diagnosis, a neurologist with neuromuscular training should combine your history, exam, and test results to identify the source of weakness. Your evaluation can include:

• A detailed exam that grades the strength of each muscle group
• Blood tests for creatine kinase, an enzyme that leaks from damaged muscle, along with thyroid and electrolyte levels
• Antibody tests when an inflammatory cause seems likely
• Electromyography and nerve conduction studies to show whether the problem sits in the muscle or the nerve
• Muscle MRI or ultrasound to find inflamed areas and choose the best biopsy site
• A muscle biopsy or genetic testing to confirm the exact type

Treatments for Staying Active and Living With Myopathy

Treatment for myopathy depends on the cause, and many people regain strength once the right plan is in place. Your care may include:

• Steroids or other medicines that calm the immune system for inflammatory types
• IVIG infusions for certain inflammatory myopathies
• Adjusting or switching a medication that affects the muscles
• Treating a thyroid or other hormone problem
• Physical therapy to protect strength and balance
• Braces, mobility aids, and home safety changes to prevent falls
