Leg pain at night from bad posture
If you feel pain in your legs when you sleep, it may be due to poor posture. As happens when we are asleep for a long time on our arm or leg and the blood circulation stops, sleeping for a long time in a certain position can lead to discomfort in the leg. These discomforts can derive from muscle, blood vessel, bone or joint discomfort and, in general, should be corrected by adopting a more comfortable posture.

Why do my legs hurt? – Injuries
An injury may cause your legs to ache when you sleep but may not be detected at the time it occurs. Some minor injuries they can go unnoticed when it happens and have symptoms later. These are some of the ones that can hide behind leg pain when sleeping:
- Muscular fatigue. Exercising without the proper warm-up or high intensity exercises can cause overloads in the muscles that later manifest with pain in the legs.
- Inflammation of the tendons. As in the previous point, a lack of stretching to prepare the muscles, bones, tendons and joints can cause an inflammation of the tendon that generates discomfort.
- Fissures. It is the breakage of a part of the bone but it does not imply its total partition, so it can go unnoticed. However, it usually causes pain if we do not keep the area immobilized.

Another reason why you wonder “why do my legs hurt when I sleep” is muscle cramps. In this case, it is possible that there are different factors that are causing the discomfort at night:

When potassium levels in the blood are lower than normal, that is, between 3.5 and 5.3 mEq / L, the body can react by causing leg cramps. This happens because this mineral plays an important role in the functioning of the nervous system, this discomfort being one of the symptoms. So if you feel pain in your legs when you sleep, consider eating foods that are richer in potassium.
