femorals

Your hip is the joint where your femur (thigh bone) meets your pelvis (hip bone). There are two main parts: a ball at the end of the femur, which fits in a socket in the pelvis. Your hip is known as a ball-and-socket joint. This is because you have a ball at the end of your femur, and it fits into a socket in your pelvis. This makes your hips very stable and allows for a wide range of motion. When they are healthy, it takes great force to hurt them. However, playing sports, running, overuse, or falling can sometimes lead to hip injuries such as:

• Strains
• Bursitis
• Dislocations
• Fractures (broken bones)

Certain diseases also lead to hip injuries or problems. Osteoarthritis can cause pain and limited motion. Osteoporosis of the hip causes weak bones that break easily. Both of these are common in older people.

Another problem is hip dysplasia, where the ball at the end of the femur is loose in the hip socket. It can cause hip dislocation. Babies who have hip dysplasia are usually born with it, but sometimes they develop it later.

Treatment for hip disorders may include rest, medicines, physical therapy, or surgery, including hip replacement.

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.

There are several types of hernias, including:

• Inguinal, in the groin. This is the the most common type.
• Umbilical, around the belly button
• Incisional, through a scar
• Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
• Congenital diaphragmatic, a birth defect that needs surgery

Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.

Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.

Your legs are made up of bones, blood vessels, muscles, and other connective tissue. They are important for motion and standing. Playing sports, running, falling, or having an accident can damage your legs. Common leg injuries include sprains and strains, joint dislocations, and fractures (broken bones).

These injuries can affect the entire leg, or just the foot, ankle, knee, or hip. Certain diseases also lead to leg problems. For example, knee osteoarthritis, common in older people, can cause pain and limited motion. Problems in your veins in your legs can lead to varicose veins or deep vein thrombosis.

Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs. Peripheral nerves carry messages from your brain that control your movement, breathing, heartbeat, digestion, and more. They also carry messages from your body to your brain, so you can feel things, such as pain, heat, and cold.

Peripheral nerve disorders happen when one or more peripheral nerves are damaged. Damaged nerves may not carry messages correctly, or they may not work at all. As a result, you may have pain, trouble walking, or a variety of other problems, depending on which nerves are involved.

Peripheral nerve disorders are very common. There are more than 100 different types.

Many things can damage nerves and lead to peripheral nerve disorders:

• Diabetes is the most common cause of peripheral nerve disorders. Most people with diabetes will develop diabetic nerve problems.
• Physical injury (trauma) that stretches, crushes, squeezes, cuts, or puts pressure on one or more nerves. Some examples of peripheral nerve disorders from physical injury include complex regional pain syndrome and brachial plexus injuries.
• Health conditions, including:
  • Certain cancers and their treatment (chemotherapy and radiation therapy).
  • Infections, such as HIV and Lyme disease.
  • Problems with blood or blood vessels.
  • Autoimmune diseases, such as rheumatoid arthritis and lupus.
  • Kidney or liver disease.
• Certain medicines.
• Contact with certain toxic substances, such as lead or mercury.
• Alcohol use disorder (AUD) and smoking.
• Vitamin imbalances, especially a lack of vitamin B12.
• Your genes, including changes in your genes or conditions that you inherit from your parents, such as Charcot-Marie-Tooth disease.

In certain cases, the cause of peripheral nerve disorder is not known.

The symptoms of peripheral nerve disorders depend on which nerves are affected, what is causing the damage, and how serious it is:

• Weak or aching muscles
• Problems with balance, walking, or using your arms and hands
• Cramps or twitching muscles
• Muscle shrinking

• Tingling, numbness, or pain often in the hands and feet
• Not being able to feel heat, cold, or pain, such as a cut on your foot
• Pain from even light touch

• A heartbeat that's too fast or too slow
• Trouble swallowing
• Sweating too much or too little
• Vomiting, diarrhea, or constipation
• Problems with urination or sexual function

Symptoms may range from mild to very strong. They may develop quickly over days or slowly over months and years. But they are rarely life-threatening.

To find out if you have a peripheral nerve disorder, your provider will:

• Ask about your medical history
• Ask about your family health history
• Do a physical exam
• Order tests, which may include:
  • Blood tests
  • Genetic tests
  • Nerve tests that measure:
    • Electrical activity in your nerves and muscles
    • How well your autonomic nerves are working
  • A biopsy of nerve or skin tissue
  • CT or MRI scan to see what may be pressing on your nerves

It's important to treat any conditions that are causing nerve damage. In certain cases, that will allow your nerves to heal over time.

Treatment for symptoms depends on the type of peripheral nerve disorder you have, where it is, and how severe. Treatment options include:

• Braces or splints
• Over-the-counter patches and skin creams
• Prescription medicines
• Non-drug pain management, such as electrical stimulation or relaxation therapy
• Surgery to relieve pressure on a nerve

You can help prevent peripheral nerve disorders by:

• Managing health conditions that may cause nerve damage, especially diabetes
• Preventing falls and accidents
• Avoiding toxic substances
• Being careful to avoid repeated motions and body positions that press on your nerves
• Eating a balanced diet, exercising, limiting alcohol, and not smoking

If you are like most people, you walk thousands of steps each day. You walk to do your daily activities, get around, and exercise. It's something that you usually don't think about. But for those people who have a problem with walking, daily life can be more difficult.

Walking problems may cause you to:

• Walk with your head and neck bent over
• Drag, drop, or shuffle your feet
• Have irregular, jerky movements when walking
• Take smaller steps
• Waddle
• Walk more slowly or stiffly

The pattern of how you walk is called your gait. Many different diseases and conditions can affect your gait and lead to problems with walking. They include:

• Abnormal development of the muscles or bones of your legs or feet
• Arthritis of the hips, knees, ankles, or feet
• Cerebellar disorders, which are disorders of the area of the brain that controls coordination and balance
• Foot problems, including corns and calluses, sores, and warts
• Infections
• Injuries, such as fractures (broken bones), sprains, and tendinitis
• Movement disorders, such as Parkinson's disease
• Neurologic diseases, including multiple sclerosis and peripheral nerve disorders
• Vision problems

To make a diagnosis, your health care provider will ask about your medical history and do a physical exam. This will include checking your bones and muscles and doing a neurological exam. In some cases, you may have other tests, such as lab or imaging tests.

Treatment of walking problems depends on the cause. If the cause is a medical condition, treating that condition often improves your walking. Some common types of treatments for walking problems may include:

• Medicines
• Mobility aids such as walkers and canes
• Physical therapy
• Special shoes, insoles, splints, or braces
• Surgery
