Knee pain

Knee pain is typically defined as discomfort, soreness, stiffness, or other unpleasant sensations in the knee area that may affect one or both knees. It can be caused by a wide range of factors including injuries, degenerative conditions, overuse or strain, infections, autoimmune disorders and other medical conditions. The severity and duration of knee pain can vary depending on the underlying cause and individual factors such as age, overall health, and lifestyle.

Symptoms of knee pain include:

Swelling and stiffness


Redness and warmth to the touch


Weakness or instability


Popping or crunching noises


Inability to fully straighten the knee

Treatment options for knee pain include:

Rest and activity modification: Reducing or avoiding activities that aggravate knee pain and allowing time for rest and recovery can help alleviate symptoms.


Medications: Over-the-counter pain relievers such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) may provide relief for mild to moderate knee pain. Prescription medications, such as opioids, may be prescribed for severe pain.


Injections: Corticosteroid injections or hyaluronic acid injections can be used to reduce inflammation and pain in the knee joint.


Assistive devices: The use of braces, sleeves, shoe inserts, or other assistive devices can help support the knee joint and reduce pain.


Surgery: In some cases, surgery may be necessary to repair damage to the knee joint, replace a damaged joint, or correct alignment issues.


Physical therapy: Exercises to strengthen muscles around the knee and improve mobility can be prescribed by a physical therapist.


Class 4 LASER THERAPY: It is a type of medical treatment that uses high-powered lasers to alleviate pain, reduce inflammation and promote tissue healing. It penetrates deeper into the body tissues than other classes of lasers and can be used to treat various conditions such as musculoskeletal injuries, arthritis, and neuropathic pain.

Class 4 LASER THERAPY for knee pain typically uses a high-powered laser to deliver energy into the tissues around the knee. When applied to the knee, the laser energy penetrates into the tissues, promoting cellular metabolism and increasing blood flow. This can reduce inflammation, relieve pain, and promote tissue repair.
