1
Neurological disorders: Examples include myasthenia gravis, ALS (Lou Gehrig's disease), multiple sclerosis, muscular dystrophy, peripheral neuropathy, and others.
2
Injuries: Such as sprains, strains, fractures, and nerve damage can result in muscle weakness.
3
Infections: Certain infections like the flu, polio, West Nile virus, and Lyme disease can cause muscle weakness.
4
Chronic conditions: Like diabetes, hypothyroidism, and anemia can lead to muscle weakness.
5
Degenerative conditions: Examples include osteoarthritis, spinal stenosis, and others.
6
Vitamin and mineral deficiencies: A lack of essential vitamins like vitamin D and B12 can result in muscle weakness.
7
Substance abuse: Overuse of alcohol and drugs can contribute to muscle weakness.
8

9
Side effects of medication: Certain medications, like statins, can lead to muscle weakness as a side effect.

It is recommended to see a neurologist if:
The weakness occurs suddenly or progresses rapidly.
The weakness is accompanied by symptoms such as numbness, tingling, or pain.
The weakness affects both sides of the body or is asymmetrical.
The weakness interferes with daily activities or significantly impacts quality of life.
The weakness is accompanied by symptoms such as slurred speech, double vision, or difficulty swallowing.
The weakness is related to a known medical condition such as multiple sclerosis, myasthenia gravis, or peripheral neuropathy.
The weakness does not improve with other treatments such as physical therapy or medications.
There is a family history of neurological conditions. A neurologist is a specialist in diagnosing and treating conditions of the nervous system, including muscle weakness. They have the expertise to determine the root cause of muscle weakness and recommend the best course of treatment.
