Rheumatic Diseases Q & A

What is rheumatoid arthritis?

Rheumatoid arthritis (RA) is a painful autoimmune disease wherein your immune system mistakenly attacks your joints, causing inflammation, swelling, difficult movement, and pain.

When RA is left untreated, the swelling and inflammation can damage the cartilage and (eventually) the bones around your joints.

What are the symptoms of rheumatoid arthritis?

Since RA is an autoimmune disease, it can affect every system in your body. Symptoms often include tender, swollen joints and joint stiffness, and sometimes fever, fatigue, and weight loss.

When RA affects other parts of your body, you may experience health problems and conditions involving anything from your skin to your bone marrow

Women between the ages of 30-60 are more likely to develop RA, and the disease puts them at higher risk for other illnesses, including lung disease and lymphoma.

How is rheumatoid arthritis treated?

There is no cure for RA, so the treatment goals include reducing inflammation, relieving symptoms, and preventing damage to your body. Dr. Zhang may prescribe nonsteroidal anti-inflammatory medications and corticosteroids, disease-modifying antirheumatic drugs (DMARDs), and other RA medications.

In more severe cases, you may need surgery to replace affected joints.

What is gout?

Like RA, gout causes painful inflammation in your joints. Gout typically comes on as a severe, sudden attack in your joints that causes swelling, redness, and tenderness.

Typically, you experience these symptoms in your big toe, making walking painful. A gout attack can feel like the affected joint is on fire — the pain is extremely intense.

Unlike RA, gout is not an autoimmune disease — it occurs when urate crystals accumulate in your joints. Urate crystals form when you have a high level of uric acid in your blood, often due to a diet rich in meat, seafood, high-fructose beverages, or alcohol — especially beer.

How is gout treated?

Gout symptoms can be controlled with medication and self-care with ice and rest. Nonsteroidal anti-inflammatory medications can help reduce swelling and pain in your affected joints.

Dr. Zhang may prescribe medications that reduce inflammation and pain, as well as those that reduce uric acid. You can take preventive measures for gout attacks such as staying hydrated and changing your diet.

What is lupus?

Lupus is a systemic autoimmune disease that can affect your skin, your vital organs, or both, depending on the type of lupus you have and the severity of your condition.

Lupus may also inflame or damage the connective tissue in your joints and muscles, and it can do the same to the membranes that surround your lungs, heart, kidneys, and brain.

Approximately 9 out of 10 people who have lupus are women, typically between the ages of 15 and 44.

What are the symptoms of lupus?

Symptoms of lupus vary, and some are temporary while others are permanent. Most lupus sufferers experience flare-ups of symptoms like:

  • Fatigue
  • Joint pain, swelling, and stiffness
  • Headache and fever
  • Skin lesions or a butterfly-shaped rash across your face
  • Poor circulation in fingers and toes
  • Shortness of breath and chest pain

How is lupus treated?

Since no single test can diagnose lupus, Dr. Zhang runs a series of tests to determine the type of lupus you have and how it is affecting your organs. Treatment depends on your symptoms, condition, and how often you have flare-ups. Dr. Zhang may prescribe nonsteroidal anti-inflammatory drugs, antimalarial drugs, corticosteroids, or immunosuppressants to help control symptoms of the disease.

What are the symptoms of fibromyalgia?

Fibromyalgia is another type of rheumatic disease that Dr. Zhang specializes in diagnosing and treating. The most common symptoms include widespread joint pain and fatigue — leading to frequent misdiagnosis since it’s hard to decipher from other conditions.

Fibromyalgia symptoms and related conditions include:

  • Fatigue and sleep issues
  • Joint pain, stiffness, swelling, and tenderness
  • Anxiety and depression
  • Concentration and memory issues
  • Numbness and tingling in your arms and legs
  • Headaches
  • Irritable bowel syndrome

How is fibromyalgia treated?

In most cases, the best course of treatment for fibromyalgia symptoms is medication and self-care. Dr. Zhang emphasizes the importance of minimizing symptoms and improving your overall health so you feel better and experience less pain.

Pain-relievers, antidepressants, and anti-seizure medications have all been effective in treating some fibromyalgia symptoms. Additionally, physical therapy and counseling may also be beneficial to those dealing with fibromyalgia.
