How sitting all day leads to knee pain

People with sedentary jobs – while driving a car or sitting in the office in front of a computer monitor – often experience joint pain during the working day or while sitting in a sitting position in general. Therefore the question as to why knees ache when sitting for a long time and what to do about it is relevant for most people of all professions. In this article you will learn how sitting all day leads to knee pain.

Possible causes

The cause of pain in the knee joint can be various ailments and pathologies, and then the symptom will indicate that the problem is sufficiently developed – in the initial stage, the diseases do not cause pronounced pain. In each case, the treatment and the healthcare professional supervising it will be different.

  • Painful sensations occur as a consequence of mechanical damage to the joint – bruises, fractures, etc. This sensation manifests itself after prolonged sitting in one place and sometimes while moving.
  • Patellar chondropathy is a common trigger of knee pain. In the course of its progression, the cartilage slowly cracks, erodes through and disappears, leaving the exposed bone unprotected. The defect is common in adolescents during the active growth phase, when the development of the limb bones does not keep pace with the formation of other skeletal elements. Chondropathy also affects pensioners whose musculoskeletal system deteriorates over time, and professional athletes who put tremendous strain on their bodies.
  • If your knees ache after prolonged sitting and are difficult to bend and straighten after changing position, you may be suffering from osteoarthritis. It impairs the structure of joints, including those in the knees and ankles. Patients suffering from this disorder are predominantly elderly, or suffer from obesity, diabetes and physical exertion.
  • One of the factors that cause discomfort is problems with local blood flow within the joint. As in the cartilage situation, this can be caused by insufficient nutrition of the growing body from the blood vessels. Often by the end of puberty, the legs stop bothering young patients.

When should you see a doctor?

Ignoring obvious health problems, when sitting in a chair causes severe pain, or self-medicating, is not a good idea. There are signs of discomfort that you should immediately make an appointment to see a doctor and get a referral for further investigation.

  • The discomfort persists for more than 3 weeks.
  • The pain comes on suddenly and sharply.
  • A crunching sound is heard when walking and standing up from the seat.
  • Pain occurs even if the patient has been sitting for only a short period of time.
  • General well-being worsens markedly, with fever and an increase in body temperature.
  • The knees swell, become red and the skin around them is hotter.
