Hello, your condition is numbness and fever in your knees. It should be that you caught a cold a few days ago, or the stress was uneven, or you were injured while running and jumping, which led to local ligament inflammation.

Guiding opinions:

Hello, your condition suggests that you go to the acupuncture and massage department or the surgical trauma department of the hospital for examination. If it is determined that there is a problem with the local ligament, it is necessary to rest and brake at present, and take local medication to avoid affecting future activities.
