OA may affect different parts of the body in different ways.

• Hips. Pain in the groin area or buttocks and sometimes on the inside of the knee or thigh.
• Knees. A “grating” or “scraping” feeling when moving the knee. 
• Fingers. Bony growths (spurs) at the edge of joints can cause fingers to become swollen, tender and red, sometimes with pain at the base of the thumb.
• Feet. Pain and tenderness in the big toe, with possible swelling in the ankles or toes.

Pain, reduced mobility, side effects from medications and other factors associated with osteoarthritis can lead to health complications that are not caused by the disease itself.

Obesity, Diabetes and Heart Disease

Painful joints, especially in the feet, ankles, knees, hip or back, make it harder to exercise. But physical activity is not only key to managing OA symptoms, it also can help prevent weight gain, which can lead to obesity. Being overweight or obese can lead to the development of high cholesterol, type 2 diabetes, heart disease and high blood pressure. 

Falls

Research indicates people with OA experience more falls and risk of fracture than those without OA. Although study results vary, some research shows they may have up to 30% more falls and have a 20% greater risk of fracture. Having OA can decrease function, weaken muscles, affect overall balance, and make falls more likely, especially among those with OA in knees or hips. Side effects from pain medications, such as dizziness, can also contribute to falls.

Medical history, a physical examination and lab tests help to make up the OA diagnosis. 

A primary care doctor may be the first person you talk to about joint pain. The doctor will review your medical history, symptoms, how the pain affects activities, as well as your medical problems and medication use. He or she will also look at and move your joints, and may order imaging. These tests help to make the diagnosis:

• Joint aspiration. After numbing the area, a needle is inserted into the joint to pull out fluid. This test will look for infection or crystals in the fluid to help rule out other medical conditions or other forms of arthritis.
• X-ray. X-rays can show joint or bone damage or changes related to osteoarthritis.
• MRI. Magnetic resonance imaging (MRI) gives a better view of cartilage and other parts of the joint.

There is no cure for OA, but medication, assistive devices and other therapies that don’t involve drugs can help to ease pain. As a last resort, a damaged joint may be surgically fused or replaced with one made of a combination of metal, plastic and/or ceramic. 

Medications

Pain and anti-inflammatory medicines for osteoarthritis are available as pills, syrups, patches, gels, creams or injectables. They include:  

• Analgesics. These are pain relievers and include acetaminophen and opioids. Acetaminophen is available over the counter (OTC); opioids must be prescribed by a doctor.
• Nonsteroidal anti-inflammatory drugs (NSAIDs). These are the most commonly used drugs to ease inflammation and pain. They include aspirin, ibuprofen, naproxen and celecoxib, available either OTC or by prescription. The OTC versions help with pain but not inflammation.
• Counterirritants. These OTC products contain ingredients like capsaicin, menthol and lidocaine that irritate nerve endings, so the painful area feels cold, warm or itchy to take focus away from the actual pain. 
• Corticosteroids. These prescription anti-inflammatory medicines work in a similar way to a hormone called cortisol. The medicine is taken by mouth or injected into the joint at a doctor’s office.
• Platelet-rich plasma (PRP). Available from a doctor by injection, this product is intended to help ease pain and inflammation. This is not approved by the Food & Drug Administration and evidence is still emerging, so discuss it with your doctor before trying it.
• Other drugs. The antidepressant duloxetine (Cymbalta) and the anti-seizure drug pregabalin (Lyrica) are oral medicines that are FDA-approved to treat OA pain.

Exercise

Movement is an essential part of an OA treatment plan. Getting 150 minutes of moderate-to-vigorous exercise per week should be the goal, according to the U.S. Department of Health and Human Services. A good exercise program to fight OA pain and stiffness has four parts:

• Strengthening exercises build muscles around painful joints and helps to ease the stress on them. 
• Range-of-motion exercise or stretching helps to reduce stiffness and keep joints moving.
• Aerobic or cardio exercises help improve stamina and energy levels and reduce excess weight.
• Balance exercises help strengthen small muscles around the knees and ankles and help prevent falls.

Talk to a doctor or physical therapist before starting a new exercise program.

Weight Loss

Excess weight puts additional force and stress on weight-bearing joints, including the hips, knees, ankles, feet and back, and fat cells promote inflammation. Losing extra weight helps reduce pain and slow joint damage. Every pound of weight lost removes four pounds of pressure on lower-body joints.

Physical Therapies and Assistive Devices
Physical therapists, occupational therapists and chiropractors can provide:

• Specific exercises to help stabilize your joints and ease pain.
• Information about natural treatments and products that can ease pain.
• Instruction to make movement easier and to protect joints. 
• Braces, shoe inserts or other assistive devices.

Surgery

Joint surgery can improve pain and function. Joint replacement surgery replaces damaged joints to restore mobility and relieve pain. Hips and knees are the joints most commonly replaced. An orthopedic surgeon can determine the best procedure based on how badly damaged the joint is.

Practicing these habits can slow down OA, keep you healthier overall and delay surgery as long as possible. It is important to pursue a number of different self-care approaches simultaneously. They are listed below.

Maintain a Healthy Weight

Excess weight worsens OA. Combine healthy eating with regular exercise to maintain a healthy weight.

Control Blood Sugar

Many people have diabetes and OA. Having high glucose levels can make cartilage stiffer and more likely to break down. Having diabetes causes inflammation, which also weakens cartilage.

Maintain Range of Motion

Movement is medicine for joints. Make a habit of putting your joints through their full range of motion, but only up to the point where it doesn’t cause more pain. Gentle stretching, raising and lowering legs from a standing or seated position, daily walks and hobbies such as gardening can help. But listen to your body and never push too hard.

Protect Joints

Make sure to warm up and cool down when doing exercise. If you play sports, protect joints with the right gear. Use your largest, strongest joints for lifting, pushing, pulling, and carrying. Watch your step to prevent falls. Balance rest and activity throughout the day.  

Relax

Find ways to reduce or avoid stress through meditation, listening to music, connecting with friends and family, doing fun activities, and finding ways to relax and recharge.

Choose a Healthy Lifestyle

Eating healthy food, balanced nutrition, not smoking, drinking in moderation, and getting good sleep will help you to feel your best.

The four stages of osteoarthritis are:

• Stage 1 – Minor
  • Minor wear-and-tear in the joints
  • Little to no pain in the affected area
• Stage 2 – Mild
  • More noticeable bone spurs 
  • The affected area feels stiff after sedentary periods
  • Patients may need a brace
• Stage 3 – Moderate
  • Cartilage in the affected area begins to erode 
  • The joint becomes inflamed and causes discomfort during normal activities 
• Stage 4 – Severe
  • The patient is in a lot of pain
  • The cartilage is almost completely gone, leading to an inflammatory response from the joint
  • Overgrowth of bony spurs (osteophytes) may cause severe pain
