Knee Pain
You cannot flex your knee or have trouble straightening it all the way out. You have a fever, redness or warmth around the knee, or a lot of swelling. You have pain, swelling, numbness, tingling, or bluish discoloration in the calf below the sore knee.
Knee pain is pain or discomfort you feel in or around your knee joint.
Joints are places in your body where two bones meet. Your knee joint connects your thigh to your lower leg. It’s where your thigh bone (femur) meets your shin bone (tibia).
The knee is the biggest joint in your body, and it absorbs and supports a lot of your weight as you move. That’s why it’s one of the most commonly injured joints. Knee pain can be a temporary, short-term problem, but it can also be a chronic (long-term) issue that needs diagnosis and treatment by a healthcare provider.
