Your legs are the foundation of your mobility, supporting your entire body weight and allowing you to walk, run and do daily activities. They are complex structures that are made up of:
- Bones
- Tendons
- Ligaments
- Muscles
- Nerves
These components all work together to provide you with:
- Strength
- Flexibility
- Balance
Pain in the legs, knees or feet is a common complaint and can affect people of all ages and abilities. These issues can range from minor discomfort to debilitating conditions, having a significant impact on a person’s quality of life. Several factors can contribute to this prevalence, including:
- Overuse injuries
- Age-related wear and tear
- Obesity
- Accidents or trauma
- Underlying medical conditions.
Understanding the common causes and symptoms of leg, knee and foot pain is crucial for effective treatment and prevention. There are effective treatment options, including physical therapy, that can help you address the underlying issue causing your pain.
Possible causes of leg, knee and foot pain
Leg pain can sometimes radiate to or cause discomfort in the knee or foot too. Here are some types of leg pain and their potential to affect the knee or foot:
- Osteoarthritis — Osteoarthritis is a degenerative joint disease that occurs due to the breakdown of cartilage. It can cause pain, stiffness and a reduced range of motion in the affected joints, like the knees, hips, ankles and feet.
- Rheumatoid arthritis — Rheumatoid arthritis is an autoimmune disease that causes inflammation in the joints. It can affect multiple joints, like the knees, hips, ankles and feet, causing:
- Pain
- Stiffness
- Swelling
- Joint deformity
- Gout — Gout is a type of arthritis caused by a buildup of uric acid crystals in the joints. It mainly affects the big toe but can affect other joints, including the knees and ankles. It can cause:
- Severe pain
- Inflammation
- Redness
- Peripheral arterial disease (PAD) — PAD is a circulatory condition that happens when the arteries that carry blood to the legs become narrowed or blocked, reducing the blood flow. Symptoms can include:
- Leg pain
- Cramping
- Numbness
- Weakness
- Cold feet
- Deep vein thrombosis (DVT) — DVT is a serious condition that involves a blood clot in a deep vein, often in the leg. It requires immediate medical attention due to the complications it can cause if the clot dislodges and travels to the lungs. DVT causes the following symptoms:
- Swelling
- Pain
- Redness
- Warmth in the affected leg
- Diabetic neuropathy — Diabetic neuropathy is nerve damage that is caused by diabetes. It can lead to:
- Pain
- Numbness
- Weakness in the legs and feet
- Meniscus tear — The meniscus is a C-shaped disc of cartilage that helps cushion the knee joint. A meniscus tear can cause:
- Pain
- Swelling
- Locking
- Popping
- Instability
- Patellofemoral pain syndrome — Also known as runner’s knee, this condition involves pain around the kneecap, usually caused by overuse, imbalance in the muscles surrounding the knee, or misalignment.
- Bursitis — Bursitis is a condition in which the bursae, small, fluid-filled sacs that help prevent friction in joints like the hip, knee or foot, become inflamed. Inflammation of the bursae can be caused by injury and overuse.
- Plantar fasciitis — Plantar fasciitis is caused by inflammation of the plantar fascia, the thick tissue on the bottom of the feet connecting the heel bone to the toes. It can cause heel pain that can also radiate into the ankle and potentially affect the knee.
- Achilles tendinitis — Inflammation of the Achilles tendon, the tissue connecting the calf muscle to the heel bone, is known as Achilles tendinitis. It can affect the ankle and potentially the knee. Symptoms include:
- Pain
- Stiffness
- Swelling in the back of the ankle
- Sciatica — Sciatica is caused by the irritation of the sciatic nerve, which runs from your lower back down through your legs. This nerve pain can radiate from the lower back through the leg, affecting the knee and foot.
These are some examples of conditions that can cause pain in and around your leg, knee and feet. If you’re experiencing persistent or severe symptoms, it’s important to consult a health care professional for a proper diagnosis and treatment plan.
When to be concerned about leg, foot and knee pain
While some leg pain that can also affect your knees or feet can be managed at home, there are times when seeking medical attention is crucial. You should see a doctor immediately if you have:
- Sudden and severe leg pain
- An inability to bear weight
- Open wounds or visible bone or tendon
- Signs of infection, such as:
- Redness
- Warmth
- Swelling
- Pus around the affected area
If you’re not sure whether you should seek medical attention, it’s always better to err on the side of caution and get checked out. Early diagnosis and treatment can help prevent complications and promote faster recovery.
Treatment options for leg, knee and foot pain
The treatment for leg, knee and foot pain depends on the underlying issue. Some common approaches to help manage pain include:
- PRICE method — The PRICE method is a general guideline for initial care of acute injuries. PRICE stands for:
- Protection — Avoid activities that worsen the pain.
- Rest — Give the injured area time to heal.
- Ice — Apply ice packs to reduce swelling and numb pain.
- Compression — Use a compression bandage to help support the injured area.
- Elevation — Raise the injured limb to help reduce swelling.
- Medications — Over-the-counter pain relievers like ibuprofen or acetaminophen can help alleviate pain and inflammation. Depending on the underlying issue and severity of your symptoms, your doctor may prescribe stronger pain relievers or muscle relaxants.
- Physical therapy — A physical therapist can design a personalized treatment plan tailored to your specific condition and recovery goals.
- Orthotics and braces — These can include custom-made inserts or supportive devices that can help correct foot alignment and reduce pressure on your joints.
- Corticosteroid injections — In some cases, your health care provider may recommend corticosteroid injections. These are steroid injections that can help reduce inflammation and provide temporary relief for conditions such as arthritis or bursitis.
- Surgery — In severe cases, your health care provider may recommend surgery. Surgeries can range from arthroscopy to help diagnose and treat joint problems to joint replacements if the damage is severe.
It’s important to consult with a health care professional for a proper diagnosis and treatment plan.
Physical therapy techniques for leg, knee and foot pain
Physical therapy is a beneficial treatment approach for many conditions that can be behind your leg, knee and foot pain. Your physical therapist will ask you about symptoms you’re experiencing and perform a thorough physical evaluation, then create a personalized treatment plan tailored based on your specific condition. Common techniques used in a physical therapy treatment plan for lower limb pain include:
- Therapeutic exercises — To help restore strength and mobility, your physical therapist may prescribe specific exercises tailored to your condition. These exercises may include:
- Range-of-motion exercises
- Strengthening exercises
- Stretching exercises
- Balance exercises
- Aerobic exercises
- Proprioceptive exercises
- Manual therapy — Manual therapy is an umbrella term for many hands-on techniques your physical therapist may incorporate to address underlying causes of pain and stiffness. These hands-on techniques include:
- Soft tissue mobilization — Soft tissue mobilization involves your physical therapist using their hands to knead and manipulate soft tissue to help reduce pain and improve flexibility.
- Joint mobilization — Your physical therapist may apply gentle but firm movements to your affected joints to help improve your range of motion and reduce stiffness.
- Myofascial release — Myofascial release focuses on releasing tension in the fascia, a connective tissue that surrounds the muscles. This technique can help improve flexibility, reduce pain and restore normal movement patterns.
- Postural education — Postural education can help you understand and fix bad posture habits that can cause strain on your joints. Improving posture can alleviate strain and reduce pain. Your physical therapist can teach you how to use good posture to promote proper body alignment and movement patterns.
- Electrical stimulation — Your physical therapist may use electrical stimulation to help reduce your pain, muscle spasms and inflammation. Electrodes are placed on your skin around the affected area and deliver low-level electrical currents to help stimulate muscles and nerves.
- Aquatic therapy — Aquatic therapy provides a low-impact environment, reducing stress on your joints while allowing for effective movement during exercises. It can be beneficial for people with arthritis or joint pain.
- Dry needling — Dry needling is a technique that should be used by a certified practitioner only. A certified physical therapist will manually insert thin, sterile needles into trigger points, troublesome spots in the muscles. This technique can help release muscle tension, reduce pain and improve muscle function by stimulating muscle relaxation.
- Instrument-assisted soft tissue mobilization (IASTM) — Your physical therapist may use specialized tools to break down scar tissue and adhesions. IASTM can help improve blood flow, reduce pain and restore normal tissue function.
Remember, these techniques are just a starting point. Your physical therapist will tailor your treatment plan to your specific needs and goals.
