Joint pain follows inflammation, such as tendonitis or arthritis. Let’s put the scenario: you want to eat an apple on the table.
- Step 1: You saw the apple on the table, and the message received on the brain was “The apple is there, I want to eat it”.
- Step 2: The brain sends a message to the leg muscle to stand up and walk to the table.
- Step 3: Leg muscles will pull tendons to move bone at the joint: the movement commences.
Under normal circumstance, muscle pulls tendon only when it requires movement.
But if your muscle is already over-contracted, it continuously pulls the tendon; the pulling is bad enough to produce irritations but not strong enough to move the bone, and (eventually) start ripping it off from the bone. (That condition is called tendonitis).
As a result, inflammation at the tendon (tendonitis), inflammation at the joints (arthritis) and inflammation in the bursa (bursitis) happen. Patients will find that the pain worsens with movement after prolonged rest. Some examples: standing up from the sitting position, getting out of the car, getting out of the bed.
