Experiencing delayed muscle weakness after exercise is something others with MG can relate to. With MG, muscles tend to weaken with repeated or prolonged use, and recovery can be unpredictable — so feeling worse on day two isn't unusual.
This happens because MG affects the way nerves and muscles communicate. When muscles are pushed during exercise, that communication breaks down further, and it can take longer than expected to recover. A few things worth keeping in mind:
- Listen to your body — if day two feels worse, that's a signal to scale back intensity or duration
- Rest between sessions — giving muscles more recovery time can help prevent worsening weakness
- Watch for warning signs — drooping eyelids, trouble holding your head up, or breathing/swallowing difficulties mean you should stop and seek medical advice
- Avoid exercising during flare-ups — this can make things significantly worse
Since your diagnosis is still unclear, it's especially important to track your symptoms and share this pattern with your healthcare team. A symptom log noting when weakness peaks after activity could be really valuable for them.
