What are you sitting on today? If it’s your foot, check this out.
Many people have the habit of perching on one foot while sitting, but that can cause trouble later.
Sitting on your foot can lead to pain in the knee, hip, ankle, back, ligament strain, Sciatic impingement, and even neck pain, as the wedge of your foot throws your alignment out of balance. It compresses nerves and blood vessels causing signal interruptions and twisting of tendons that can affect your gait.
If you are a foot sitter, try getting both feet flat on the floor.
Raise your knees to the level of your hips, by adjusting the height of your seat. You might try a foot stool to accomplish this.
If you do this to keep your foot warm, I recommend woolly socks.
