“What should I do to ease my pain from a hyper extended knee?”

I would focus on reducing any swelling, if there still is any, using some muscle stimulator device like a Compex or Marc Pro. Once the swelling is down, the focus must be on training muscle endurance and strength for the musculature surrounding the injury, such as the hamstring, calf, and quad. Isometrics and proprioception training are highly beneficial. Avoid full extension of the knee during rehab exercises until the pain subsides, and treat pain with modalities such as dry needling, soft tissue massage, and red light/laser light therapy. Hope this helps!

Thank you for your question, at this time you’re in the subacute state. I will recommend starting with conservative management including passive and some active range of motion exercises on strengthening protocols. If you notice increase inflammation, swelling or restriction on your range of motion you should consult your doctor.

Although you may have experienced a simple knee sprain, it is also possible that your injury is more severe. A knee sprain would typically get better with rest, NSAIDs, and time. However, a more severe injury like a meniscus tear or ACL injury could lead to more long term complications and should be evaluated by a musculoskeletal specialist. After 3 weeks of continued pain, I would suggest seeing your doctor. You may need an MRI to rule out a more serious injury.

Initially after an injury it is recommended that you ice, elevate and rest the injured area. After about 3-4 days you can slowly start rehabilitation exercises and gradual return to activity depending on the severity of the injury. If you are still having pain 3 weeks out then I recommend you get a full in office examination and assessment with a doctor with expertise in sports medicine.
