Rheumatoid Arthritis: Symptoms, Causes, and Foot Care

Rheumatoid arthritis is a chronic inflammatory autoimmune condition that affects not only the joints but the entire body. The disease causes persistent inflammation that can damage joints, tissues, and organs over time.

Although rheumatoid arthritis cannot be fully prevented, certain risk factors—such as smoking—can increase the likelihood of developing the disease.

The small joints of the hands and feet are most commonly affected. As the disease progresses, joint mobility becomes increasingly limited and everyday activities may become painful. Proper joint protection and supportive footwear, including DrLuigi® comfort shoes, can help reduce strain on sensitive joints and improve daily comfort.

What Happens in Rheumatoid Arthritis?

Rheumatoid arthritis often begins years before visible symptoms appear. In the past, joint swelling was believed to mark the beginning of the disease. Today we know that the earliest changes occur in the synovium, the membrane that lines and protects joint cartilage.

The synovium produces synovial fluid, which nourishes cartilage and supplies oxygen and nutrients to the joint. In rheumatoid arthritis, inflammatory cells accumulate in this fluid, triggering chronic inflammation.

These cells release enzymes that gradually break down cartilage tissue. Over time, abnormal inflammatory tissue called pannus forms and begins to destroy collagen and joint structures.

As cartilage deteriorates, several symptoms develop:

• Joint swelling

• Persistent pain

• Reduced joint mobility

Laboratory tests often show elevated levels of Rheumatoid factor and C-reactive protein, both indicators of systemic inflammation.

Because rheumatoid arthritis affects the entire body, management requires a comprehensive approach that includes medical treatment, lifestyle adjustments, and supportive footwear such as DrLuigi® medical slippers to reduce pressure on sensitive joints in the feet.

Common Symptoms of Rheumatoid Arthritis

Symptoms usually develop gradually and may sometimes follow an infection. In a smaller number of cases, the disease may begin suddenly and affect multiple joints at once.

In addition to joint symptoms, many patients experience systemic symptoms such as:

• Fatigue

• Excessive sweating

• Mild fever

• Loss of appetite

• Weight loss

• Persistent joint pain

Joint Symptoms

Rheumatoid arthritis primarily affects the joints.

Morning Stiffness

Morning stiffness is one of the most characteristic symptoms of rheumatoid arthritis. It is most noticeable in the hands but can also affect the feet, knees, and ankles.

Stiffness is typically strongest after waking and gradually improves with movement. As the disease progresses, stiffness lasts longer and pain becomes more intense.

Joint Swelling and Pain

Initially, pain appears mainly when pressure is applied to the joints. Over time, swelling (edema) develops and becomes more persistent.

The swelling is usually symmetrical and commonly affects:

• Metacarpophalangeal joints

• Proximal interphalangeal joints

The Cervical spine may also be affected, causing neck pain and reduced mobility.

In the lower body, rheumatoid arthritis frequently affects the knees, feet, and sometimes the hips. Ankles may become swollen and less mobile.

As the disease progresses, structural deformities can occur, including Hallux valgus. Proper foot support becomes especially important at this stage, and cushioned footwear may help reduce pressure on inflamed joints.

Non-Joint Symptoms

Rheumatoid arthritis can affect many organs and systems in the body.

Skin Changes

Patients may develop firm, painless nodules under the skin, known as rheumatoid nodules. These commonly form at pressure points and are more frequent in patients with elevated rheumatoid factor levels.

If nodules develop near tendons, they may interfere with normal movement.

Blood Vessel Inflammation

RA may also cause Vasculitis, which reduces oxygen supply to tissues (ischemia). When circulation is compromised, the feet may become more vulnerable to ulcers and tissue damage.

Eye Inflammation

Inflammation of the eye, such as Episcleritis, may cause redness and irritation, although it usually does not affect vision.

Nervous System Involvement

Peripheral nerves may also be affected, leading to sensory or motor disturbances. Long-term inflammation can additionally weaken bones and increase fracture risk.

Supporting Foot Health in Rheumatoid Arthritis

Because rheumatoid arthritis frequently affects the joints of the feet, protecting these joints is an important part of daily management.

Supportive footwear can help:

• Reduce pressure on inflamed joints

• Improve stability while walking

• Minimize pain and fatigue

• Protect joints from additional strain

Comfortable and supportive footwear such as DrLuigi® comfort shoes can provide cushioning and stability, helping people with rheumatoid arthritis maintain mobility and improve everyday comfort.
