Calf Cramps and cramps in legs and feet

Calf Cramps with Pain

Here there is often either Liver Blood Stasis and/or a history of injury. Injury prevents the smooth flow of Qi and Blood, starving the tissues and leading to calf cramps.

Cramps with Numbness

Numbness is a further extension of Blood deficiency.

Here you get what is called Empty Wind, which arises because the Blood, being deficient and not properly flowing, can’t prevent ‘bubbles’ appearing in it.

Please realise that these aren’t real bubbles!

 They are a figure of speech to explain the idea of Empty Wind. If you have ever seen a river during drought, as the water flows over the river bed there are many small obstacles for it and it makes a noise, as bubbles form and collapse, quite different from the noise of the full river.

Another way of thinking about it is this. If your blood is deficient, it cannot feed your nerves, so they don’t send your the correct messages, and you feel numb. By calling it Empty Wind, Chinese medicine identifies the underlying cause which is deficient Blood.

You may feel this as a tingling or slight quiver in your toes or muscles which warns you that they are working up to a cramp.

‘Mending’ the Blood deficiency leads to improvement in the numbness.

Age and Cramps

Ageing brings wisdom but, often, physical woes.

One of them is that our supply of Jing gradually reduces. This means that, among other problems, our digestion becomes less efficient. With a less efficient digestion (Spleen and Stomach) we don’t make such good Blood.

What can you do about Leg, Foot and Calf Cramps?

For more details read the linked pages detailed above.

In general, however, keeping fit helps.

• So taking enough food – from good sources – preparing. presenting and chewing it well in restful surroundings or company, is a first step.

• Exercise is good, because it moves Qi and Blood, Heart Qi and Liver Qi and helps to prevent Qi stagnation. When your legs spasm, as in a leg or calf cramp, Qi has stopped moving, and once you’ve released the tension, you need to move the leg to ease it. Exercising regularly keeps your leg tissues in better shape. Walking fast, daily, for half an hour or so has been tried for millennia and is still effective. The worst thing you can do is sit for hours at a desk!
• Don’t forget exercises for strength and flexibility of your back and abdomen, which protect your core energies.
• Passive exercise, such as regular massage, helps many, but it does not completely replace exercise, because exercise makes the whole of your body more efficient by stimulating the interaction of yin and yang, Qi and Blood.
• Before bed make sure you are warm. Cold extremities slow the progress of Blood, meaning your legs and calves don’t get the sustenance they need.

Nutrition

• Depending on a range of variables, a snack before bed may help. Nuts, such as brazils, hazels and almonds are highly concentrated foods that also contain good fats. If you aren’t allergic to them they can provide both warmth and nutrients you need, and you don’t need many (5 or 10 at most) at bed time. Or a milky drink. These help guard against Blood deficiency and if the drink is warm, against cold. The Zinc in the nuts also probably helps support Kidney Jing.
• Continuing the theme of nutrition: bear in mind that cramps are more yang than yin, in that we want to relax (yin) the spasm (yang). We emit carbon dioxide as we exhale, replacing it with oxygen on inhalation. Oxygen is yang compared to carbon dioxide, which is comparatively yin. (Why? Because oxygen gives us life: it cheers us and raises our spirits. Too much and we become hyper.) A possible cause of cramp is yin deficiency caused by lack of carbon dioxide. So, for some, inhaling carbon dioxide for a short while may help the cramp. How? Inflate a paper bag by breathing out into it and in from it. That way you will re-inhale carbon dioxide, which may help put it back into your blood, so relaxing the cramp. This may explain why some people wake from sleep with terrible cramp, possibly caused by lack of enough movement to generate the gas in the blood stream yet breathing out what remains.

• If you take supplements, such as of Magnesium, be sure to take a recommended mixture of substances (eg, Magnesium, D3, K2, Boron, Calcium) that work together to increase good absorption of each. Long-term, consider what I’ve written on my page on supplements.

Excitement

• Don’t get excited by reading or watching thrillers before bed. For some people the emotions disrupt their Qi circulation and can, in susceptible individuals, lead to Qi and Blood stagnation.
• See also under ‘weather’ below.

Light – the wrong kind

• Don’t use computers or tablets or phones before bed. Viewing these seems to use up Liver Blood very quickly. As Liver Blood deficiency leads to calf cramps, if you use computers (or VDUs or small screens) you set yourself up for them. Another way of looking at this is to say that we are drawn to yang things like the flickering screens and the ever-changing messages on them. Too much yang exposure uses up our yin resources, one of which is Blood. Hence we get Blood (yin) deficient-caused cramp.

Emotions

• Try to sort out emotional problems before going to bed. Then Qi stagnation won’t trouble you when you are trying to sleep.
• If Stress and Emotional tensions are real problems for you, consider seeing someone for counselling – even a friend may be able to help. And you might benefit from reading my book ‘Qi Stagnation – Signs of Stress’, for links to which see side panel.

Weather

• Some people are affected by wind. In Chinese medicine, Wind is a major cause of disease, much more important than we in ‘developed’ countries believe or accept. Sometimes a draft through a room, or windy weather, is all it takes to set off all sorts of health problems, including coughing (which is another kind of spasm) AND, in this case, cramps in your calves.
• There’s another kind of wind too, which links back to the emotional tensions mentioned above. This occurs when an unexpected word from a partner, or some unwelcome event seems to disarray us. Its effect is like a sudden draft, as it were making a door in our mind ‘bang’. And that sets off the cramp. This kind of (usually ) sudden event acts like Wind. You may not even be aware of it at the time, but perhaps retrospective consideration will reveal it. And if  you haven’t clicked the link to Wind yet, Wind has a disproportionate effect on your Liver. Usually it’s your Liver that, in Chinese medicine, produces calf cramps.
