Leg Swell and Night Cramps at the end of the day?

Why do the legs swell at the end of the day and there are night cramps?

Let’s say right away: that there are several answers to this question. The answer is correct, why exactly do you have swelling or convulsions can only the doctor after a personal examination, history taking and examination.

First, let’s look at the terminology. Edema is the accumulation of excess fluid in soft tissues, and cramp is an involuntary contraction of muscles. Of course, the combination of these two unpleasant symptoms suggests the thought of impaired venous outflow. Did your parents have varicose veins? Are your veins okay? Are there any visual manifestations of protruding veins or vascular mesh? Do you belong to the “risk group” of venous diseases? In any case, we repeat, we recommend that you consult a doctor and find out the exact cause of edema and seizures.

Swollen legs are not always a symptom of serious illness. So your body can react to stress, for example, during a flight or a walking trip for too long. In addition, many pregnant women, overweight people, and office workers who lead a sedentary lifestyle face this unpleasant phenomenon.


Let’s briefly examine the causes of edema of the lower extremities.

  • Uncomfortable shoes lead to swelling: high heels, too tight or too loose shoes. Clothing, for example, too tight jeans or crushing socks, may also be affected.
  • During pregnancy and premenstrual syndrome, due to hormonal changes, edema often occurs in the area of ​​the feet and legs.
  • Orthostatic is called edema, which occurs in the evening for people who are long-standing. After a rest, they should fully pass.
  • The next category is cardiac or cardinal swelling of the legs, due to various heart diseases.
  • This may be a violation of lymphatic drainage, for example, in inflammatory lesions of the lymphatic vessels or the manifestation of elephantiasis.
  • Against the background of serious neurological and endocrine diseases, edemas also appear. Diseases of the intestines or kidneys, too, can manifest in the form of edema, here it is necessary to take into account the accompanying symptoms.
  • The next category of leg edema arises from inflammatory processes, as well as a reaction to insect bites or poisonous creatures.
  • So-called drug edema is one of the side effects of taking medications, such as estrogen or reserpine.
  • The last and main cause of swelling of the legs is a violation of the venous outflow: varicose veins, inferior vena cava syndrome, and thrombophlebitis. Found a swelling? First of all, we recommend excluding the development of varicose veins. Make an appointment with a phlebologist and be sure to watch for the occurrence of other manifestations: spider veins, heaviness in the legs, pruritus, aching pains and night cramps, which we will discuss later.


Cramps most often occur at night. This may be a one-time phenomenon and may be periodically repeated. Do not worry if you have experienced a one-time spasm, perhaps because of overwork and uncomfortable posture for sleeping. But systematic, painful and long-lasting involuntary muscle contractions, especially in conjunction with edema, are an important reason to consult a specialist.

Let’s now examine the possible causes of cramps.

  • Many reasons are related to your lifestyle. Nervous tension, sedentary work, too long and active walking, dehydration of the body – all this can lead to convulsions. And of course, when they occur, the lifestyle should be reconsidered.
  • Often, cramps can occur due to malfunctioning calcium channels, because to reduce our muscles, we need sodium, potassium and magnesium cations.
  • Convulsive contractions of the musculature of the leg sometimes cause club foot and distortion in the ankle joint.
  • Another disease is polyneuritis, which affects the nerves, due to viruses, intoxication, hypovitaminosis, and metabolic disorders in diabetes mellitus.
  • As with edema, there are medical causes of cramps. For example, drugs that lower blood pressure and improve the cardiovascular system may remove too much potassium from the body. Whatever drugs you take, tell about the occurrence of seizures to your doctor.
  • The next group of diseases leading to convulsions develops due to similar reasons. Here we will assign varicose veins, venous insufficiency, thrombophlebitis and even hemorrhoids, also arising from a sedentary lifestyle, work patterns, poor diet, heredity, and so on.
