Muscle Weakness: What's Causing It and How It's Treated

Muscle weakness isn't just about being "out of shape." When an arm or leg suddenly feels heavy, when you can't grip like you used to, or when you trip over your own feet, something is going on beneath the surface — often with the nerves that control those muscles.

Muscle Weakness vs. Fatigue

These are not the same thing, and the distinction matters. Fatigue is a feeling of tiredness that improves with rest. True muscle weakness is a reduced ability to generate force — you push as hard as you can and the muscle simply doesn't respond the way it should. If that sounds familiar, it's worth getting evaluated.

Common Causes of Muscle Weakness

Nerve Compression

A pinched or compressed nerve — in the neck, back, or along an extremity — interrupts the signal that tells a muscle to fire.

Neuropathy

Peripheral nerve damage, often from diabetes or chemotherapy, commonly causes weakness alongside numbness and tingling.

Spine Conditions

Herniated discs, spinal stenosis, and degenerative changes can all press on the nerves that supply the arms and legs.

Deconditioning & Disuse

After injury, surgery, or a long period of inactivity, muscles lose strength — but they can be retrained.

How We Approach Muscle Weakness

At Texas Nerve and Spine, we start with a functional and neurological evaluation to pinpoint where the signal is breaking down. From there, we build a plan that combines therapies aimed at restoring both nerve function and muscle strength.

Don't Wait to Be Evaluated

Progressive weakness — especially with numbness, balance problems, or trouble with everyday tasks — deserves prompt attention. The sooner the cause is identified, the more options you have for restoring function.
