HOME CARE ADVICE FOR A MILD KNEE PAIN
And remember, contact your doctor if you develop any of the "Call Your Doctor" symptoms.
- Knee Pain after Overuse: Muscle strain and joint irritation are very common following vigorous activity. Such activities include sports like tennis and basketball, jogging, and certain types of work.
- Local Cold: Apply a cold pack or ice bag (wrapped in a moist towel) to the area for 20 minutes. Repeat in 1 hour, then every 4 hours while awake. Continue this for the first 48 hours after an overuse injury (Reason: reduce the swelling and pain).
- Local Heat: Beginning 48 hours after an injury, apply a warm washcloth or heating pad for 10 minutes three times a day to help increase circulation and improve healing.
- Rest Your Knee for the next couple days. Avoid activities that worsen your pain. Reduce activities that put a lot of strain on the knee joint (e.g., deep knee bends, stair climbing, running).
- Pain Medication:
- For pain relief, take acetaminophen or ibuprofen.
- Acetaminophen (e.g., Tylenol): The dose is 650 mg by mouth every 4 hours or 1000 mg by mouth every 6 hours. Maximum dose per day = 4000 mg.
- Ibuprofen (e.g., Motrin, Advil): The dose is 400 mg by mouth every 6 hours or 600 mg by mouth every 8 hours.
- People who are over 65 Years of age: Acetaminophen is generally considered safer than ibuprofen. Acetaminophen dosing interval should be increased to every 8 hours because of reduced liver metabolism. Maximum dose per day = 3000 mg.
- CAUTION: Do not take ibuprofen if you have stomach problems, kidney disease, are pregnant, or have been told by your doctor to avoid this type of anti-inflammatory drug. Do not take ibuprofen for more than 7 days without consulting your doctor.
- CAUTION: Do not take acetaminophen if you have liver disease.
- Read the package instructions thoroughly on all medications that you take.
- Expected Course: If your knee pain does not get better during the next week or if it recurs, then you should make an appointment with your doctor.
- Call Your Doctor If:
- Knee pain persists longer than 7 days
- You become worse
