4 Symptoms of Knee Pain
Redness
When your knee pain is caused by an injury or inflammation, it would lead to the discoloration in the surrounding areas. This can be noticed easily with the redness on the skin. It suggests that your body is trying to protect and heal the cells against the inflammation. Some possible triggers of this sign include fractures, muscle tear or stretch, bursitis, or arthritis. The redness might also be accompanied by the warm sensation in the affected area. If it does not improve after a few days, make sure to see your doctor for medical treatments. [6]
