Always cramping and don’t know why? Sometimes you tell your muscles what to do, but they do their own thing, such as pulsing or contracting, and can’t relax. Twitches and cramps are most common in the thighs, calves, hands, arms, abdomen, chest and arches of the feet. They may involve some of the muscles, all of them or a group of muscles. Doctors are often unable to determine why they occur, but some common triggers may cause them.1. Eyelid twitches These twitches can occur in your upper or lower eyelids, causing you to feel annoyed. Triggers of can be stress, smoking, wind, bright lights, too much caffeine and lack of sleep. The twitches are annoying but harmless and usually go away quickly, but return in the next few days. Twitching that lasts more than a few days may be a sign of an eye problem, such as dry eyes or glaucoma.2. Facial spasms can also occur if you are experiencing problems that affect the movement of the muscles in your face. In rare cases, twitching may be a sign of a brain or nervous system disorder, such as Bell’s palsy, multiple sclerosis and Tourette’s syndrome, but these conditions can also cause other symptoms.3. Low electrolytesMuscles rely on minerals (such as potassium and magnesium) to work properly, and the body will send you messages of cramps and spasms if there are related abnormalities. Exercise or heavy sweating may cause your body to deplete electrolytes, and certain medications can also cause you to deplete electrolytes. You may also lose too much electrolytes after diarrhea or vomiting.4. Dehydration If you don’t drink enough water, your muscles will be more likely to twitch and spasm. Not only water, but a lot of sweating, fluid loss, and electrolyte loss when you’re sick is another common cause of twitchy muscles.5. Stress Sometimes you can blame stress on a headache or insomnia, but this can also lead to muscle tension and pain. Try relaxation techniques, such as massage, to address them.6. Too much caffeineCaffeine can get you out of a slump, but too much can trigger muscle twitching in various parts of the body. Other stimulants, such as amphetamines, have the same effect. 7, lack of sleep and fatigue If you are tired or exhausted, twitching and cramping may be a way for your body to let you know. Your muscles may also feel sore and achy, or usually just weak.8. Poor fitnessIf you notice cramping after a workout or walk, you may need to spend more time building muscle and strength training at least twice a week.9. MedicationsIf you have high blood pressure or heart disease, your doctor may give you a diuretic. They make you urinate more, which lowers the amount of potassium in your body and can cause muscle cramps. Other medications, such as certain antidepressants, may cause convulsions. Some epilepsy and psychiatric drugs may make your eyelids twitch.10. Kidney diseaseThe kidneys usually do not send out warning signs that they are slowing down. When they lose much of their ability to work, you may experience muscle spasms as well as other symptoms.11. Rau-Gregor’s disease, also known as ALS muscle twitching in the hands and feet may be one of the early symptoms of this condition, also known as amyotrophic lateral sclerosis (ALS). This happens because the nerves that send messages from the brain and spinal cord to the muscles stop working and they send irregular messages before they stop sending them altogether. It is the acromegaly that Stephen Hawking obtained.
