Manage your symptoms:
- Use assistive devices as directed. These help protect you from injury. Examples include a walker or cane. Have someone install handrails in your home. These will help you get out of a bathtub or stand up from a toilet. Get help going up and down stairs if your legs are weak.
- Do range of motion exercises as directed. These exercises help increase movement in your weakened body part. This may happen if you have chronic weakness. Your healthcare provider or physical therapist will teach you exercises to do.
- Exercise and rest as directed. You may need more rest than usual. Balance rest with exercise. Exercise can help increase your muscle strength and energy. Do not exercise for long periods at a time. Too much exercise can cause muscle strain or make you more tired. Ask your healthcare provider how much exercise is right for you.
- Manage stress. Try to avoid stress if possible. Stress may make your symptoms worse.
- Eat healthy foods. Too much or too little food may cause weakness or tiredness. Ask your healthcare provider what a healthy amount of food is for you. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, lean meats and fish, nuts, and cooked beans.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can make your symptoms worse, and can cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Do not use caffeine, alcohol, or illegal drugs. These may cause muscle twitching, which could lead to worsened weakness.
