Why do muscle spasms increase in MS?
Muscle spasms can increase due to several factors related to MS and your daily life. In MS, nerve damage in the brain and spinal cord disrupts normal muscle control, creating an imbalance of chemical messengers like GABA that help calm the nervous system.
Several triggers can make spasms worse:
- Reduced movement (like when sleeping or sitting for long periods)
- Unsupported body positioning that creates extra tension
- Fatigue, which is a common trigger
- Temperature changes (extreme hot or cold)
- Stress and anxiety
- Sudden position changes or movements
- Infections, tight clothing, constipation, or a full bladder
Spasms often feel worse at night because you're moving less during sleep, and your body position in bed can add tension to muscles. The combination of tight muscles, pain, and difficulty relaxing can create a cycle that makes spasms more frequent.
Some people also notice more spasms during MS relapses. Learning to identify your personal triggers can help you manage and potentially prevent increases in spasms.
