- Chronic – Chronic pain can be defined as any pain that lasts longer than two or three months. If you’ve been living with serious knee pain for that long, you should consult with your doctor. He or she will most likely suggest performing another full physical exam, in addition to x-rays.
- Acute – Acute pain is the most intense type of knee pain. It typically occurs after an injury and will last for about a week. The treatment for acute pain is generally just to simply rest and isolate the affected area, as your body is working hard to heal it.
- Subacute – Subacute pain is typically felt two to six weeks after an injury. The affected area will still be painful, but it will not be nearly as severe as the acute pain of the first week. The treatment for subacute knee pain generally consists of gentle motions meant to increase your range of motion and facilitate healing.
