What is a muscle cramp?
A muscle cramp is a sudden, painful tightening of a muscle that you cannot release at will. It usually lasts seconds to a few minutes, and the muscle can feel hard, knotted and sore afterwards.
The calf is the most familiar place. Cramps also strike the foot, the back of the thigh, the hands and the belly of the muscle just under the ribs.
What can set cramps off?
There is rarely one cause. It is usually a mix, and the mix differs from person to person.
- Calves that are tight or tired after a long day on your feet.
- Heavy sweating in Ipoh’s heat without replacing fluids.
- A sudden jump in exercise, or an unfamiliar sport.
- Sitting or lying in one position for a long time, with the foot pointed.
- Some medicines, including some for blood pressure and fluid, so ask your doctor.
- Nerve irritation in the back or legs, and medical conditions such as diabetes.
Our blog on hydration and cramps in a hot climate covers the fluid side. The right amount of water depends on your health and your doctor’s advice.
Which kind of cramp do you have?
It helps to sort your cramps into three kinds, because the next step differs.
- Night cramps in the calf or foot. They wake you, ease within minutes and leave the muscle sore.
- Cramps during work or exercise. They show up after standing in a kitchen or on a hawker stall, after badminton, or on a hike up Bukit Kledang.
- Cramps with other symptoms. Swelling, weakness, numbness, back pain that runs down the leg, or colour change in the skin.
The third kind is the one to bring to a doctor first. The first two are where physiotherapy is most useful.
What should you do during a cramp?
Act in the first minute.
- Stop what you are doing and, if safe, stand and put weight on the foot.
- Pull the toes up towards the knee, with a towel if you cannot reach, and hold until it eases.
- Rub the muscle gently once it softens.
- Walk slowly for a minute, then sit and rest.
Avoid forcing a hard stretch, hitting the muscle or applying very hot packs. The muscle is already irritable, and rough handling can leave it sore for a day or two.
What does a physiotherapist check at home?
We start with the story: when the cramps come, how long they last, what you were doing and what you take. Then we look at the body.
We check calf and hamstring flexibility, strength in the legs and feet, how your ankles move, and how you stand and walk. We look at the back if leg symptoms point that way. At home we also see your bed, the floor you stand on while cooking and your footwear.
From that we build a plan. It may include stretches, strengthening, advice on work posture and pacing exercise. If the signs suggest a medical cause, we tell you and help you go to your doctor first.
Who is most likely to benefit?
Older adults who wake with calf cramps and then fear getting out of bed. People who stand all day, such as hawker stall and kitchen workers, teachers and factory staff. Runners and badminton players who push hard in the heat.
It also helps people whose legs are weak after illness or surgery, because weak muscles tire and cramp sooner. There is more in our page on muscle weakness.
When should you see a doctor?
See a doctor soon if one calf is swollen, red, warm or tender, especially after a long journey or bed rest. Go to the emergency department if that comes with chest pain or breathlessness.
Also see a doctor for cramps with new weakness or numbness, cramps that began after a new medicine, or cramps that keep returning with no clear trigger. A check of blood tests and medicines may be needed. If numb feet are part of the picture, our page on peripheral neuropathy explains more.
