Decreased muscle strength, where you try your best to move a limb but a normal muscle contraction doesn't occur. Muscle weakness is typically due to nerve issues or problems within the muscles.
When to See a Doctor
Seek professional care if you experience any of the following symptoms
- Weakness in arms or legs
Possible Causes
Generally, Limb weakness can be related to:
- Muscular Dystrophy
Muscular dystrophy (MD) is a group of diseases causing progressive weakness and muscle wasting. It is caused by mutated genes that normally allow healthy muscles to form. Different types of MD can appear at different ages, ranging from childhood to adulthood, and also present different levels of severity and clinical manifestations.
- Progressive Multifocal Leukoencephalopathy (AIDS-Related PML)
Progressive multifocal leukoencephalopathy (PML) is a serious neurological disorder caused by the destruction of cells that produce myelin (protective layer around nerves) in the white matter of the central nervous system (brain and spinal cord). It is caused by the reactivation of the JC (John Cunningham) virus. Most adults have been exposed to this virus, and it usually doesn't cause any problems, but people with a weakened immune system are at higher risk for developing PML. PML is typically associated with patients who have HIV/AIDS, but it can also occur in patients without HIV who have a weakened immune system for other reasons.
Neuromyelitis Optica (NMO)
Neuromyelitis optica (NMO) is a rare condition in which the immune system damages the spinal cord and the optic nerves.
- Lambert-Eaton Syndrome
- Chronic Inflammatory Demyelinating Polyneuropathy
Related Serious Diseases
Sometimes, Limb weakness may be related to these serious diseases:
- Cervical Cord Injury
Injury to the spinal cord at the neck level, often caused by falls or accidents.
- Spinal Cord Abscess
- Cerebral Venous Sinus Thrombosis (CVT)
- Encephalitis / Encephalopathy
- Pontine Infarction / Hemorrhage
Doctor's Diagnostic Questions
Your doctor may ask these questions to check for this symptom:
- Do your arms or legs feel weak?
- How long have you had weakness in your arms or legs this time?
- How long do your episodes of muscle weakness typically last?
- How quickly did the weakness in arms or legs develop?
- How has your inability to move muscles in the arms and legs changed since it started?

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
