My knee hurts when it's cold, and sometimes it hurts like jam.

In this case, if the cold weather causes knee pain, it is usually caused by the recurrence of arthritis. At the same time, it can be accompanied by synovitis around joints and chronic inflammatory stimulation of ligaments and tendons.

Guiding opinions:

It is suggested to apply magnesium sulfate hot compress locally to improve circulation and promote inflammation absorption, and take diclofenac sodium and other drugs appropriately to relieve symptoms. Pay attention to the warmth of joints. Take a joint film if necessary to see if there are any other abnormalities.
