2 Swelling
Swelling is a common symptom associated with practically any kind of knee injury – any kind of injury at all for that matter. This can be one of the first signs that something is wrong though, and therefore it is a useful indicator to look out for.
Swelling might be considered a bad thing, but in fact, it is good in that this is your body trying to combat the problem and speed up recovery. The knee swells up as the body delivers more oxygen, blood, nutrients, and antibodies to the affected area. It can then use those supplies in order to repair the tissue, while the antibodies prevent the site from becoming infected.
For these reasons, it might actually be bad advice to try and prevent swelling entirely. In fact, you might do better to use a warm compress rather than cold. Or even to use contrast therapy. This works by causing the blood vessels to dilate and contract, thereby ‘pumping’ blood and liquid to the area.
