That jittery, twitchy feeling in the mornings is something others with MG can relate to. Those small, involuntary muscle twitches are called fasciculations, and they can happen in any muscle group, including the arms.

In MG, the immune system interferes with the signals between nerves and muscles. This disruption can cause muscles to behave unpredictably, leading to twitches or that unsettled, jittery sensation.

A few things that might be contributing include:

- Muscle fatigue — even from the night before or from sleep positions
- Stress — which can tense muscles and worsen MG symptoms
- Time of day — MG symptoms can fluctuate, and mornings can sometimes be a tricky time as your body "wakes up"
- MG type — twitching may be more noticeable in people with MuSK antibody-positive MG It's worth keeping a simple symptom log noting when the jitteriness and twitches happen, how long they last, and anything that might have triggered them. Sharing that pattern with your neurologist can really help guide next steps and adjustments to your care plan.
