During a cold, if there is knee pain, it is often seen in viral colds, and the pain can often be relieved by antiviral treatment. In addition, during the period of episodic symptoms, bacterial colds are often seen, which often induce inflammation of the synovial bursa of the knee joint and show an increase in white blood cells and neutrophils during routine blood tests. This inflammation of the synovial bursa is mainly induced by external symptoms. In this case, anti-inflammatory treatment can be considered. On top of anti-inflammatory treatment, some oral non-steroidal drugs such as ibuprofen and celecoxib can be considered. In addition, for this inflammation of the synovial bursa, if the amount of fluid is too much, you can also consider extracting part of the fluid. The fluid in the knee joint is often absorbed on its own very slowly, and during this period, you also need to pay attention to the warmth of the knee joint, do not get cold, and reduce the activity and weight bearing of the knee joint.
