Theres something I've always been confused about muscle skeletal vs ms

A MyMSTeam Member asked a question 💭
Liverpool, UK

Drs, nurses and physios are quick to say my problem is muscle skeletal but the muscles only move if z nerve sends a signal... Why are muscle problems not caused by ms... The nerve could be damaged and misfiring or sending wrong signals to to the muscles

That's a really sharp observation, and honestly, it's a frustration many people with MS share. The short answer is: you're not wrong.

MS damages the myelin sheath — the protective covering around nerves in the brain and spinal cord. When that covering is damaged, nerve signals get disrupted, slowed, or misfired. Since Show Full Answer

That's a really sharp observation, and honestly, it's a frustration many people with MS share. The short answer is: you're not wrong.

MS damages the myelin sheath — the protective covering around nerves in the brain and spinal cord. When that covering is damaged, nerve signals get disrupted, slowed, or misfired. Since muscles only move when nerves tell them to, damaged nerves absolutely can cause muscle problems. Here's how MS-related nerve damage can directly affect muscles:

- Weakness — disrupted signals mean muscles don't activate properly
- Spasticity — stiffness and involuntary spasms from misfiring signals
- Poor coordination — the brain's commands don't reach muscles reliably
- Fatigue — muscles tire faster when nerve communication is inefficient

So when a healthcare provider labels something "musculoskeletal," it's worth pushing back and asking whether the nerve pathway involved could be affected by MS lesions. The distinction healthcare providers sometimes make is about *where* the problem originates — a structural joint or muscle issue versus a nerve signaling issue. But with MS, the two can overlap significantly, and nerve-driven muscle problems are very real.

Bringing this up directly with a neurologist, rather than a general physio, may get a more MS-informed response.

PS

MS does not primarily attack the muscle tissue the way muscular dystrophies do. The muscles themselves are usually structurally capable; the core problem is faulty command-and-control from the CNS. Disuse, deconditioning, and secondary fiber/metabolic changes amplify the functional deficits.

directly (from impaired neural drive) and indirectly (from reduced activity, fatigue, or secondary changes in the muscle itself)

Good question! Muscular skeletal issues are usually from joints, bones , or sore muscles not from nerves .

Thank you, im aware the muscle is as good as can be, although probably out of alignment somewhat, am i wrong in thinking that the muscle might be getting the signal its in pain due to damaged nerves, even though its fine?
