Information for Patients

Infectious Arthritis

Also called: Septic arthritis

Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Infectious arthritis is an infection in the joint. The infection comes from a bacterial, viral, or fungal infection that spreads from another part of the body. Symptoms of infectious arthritis include

  • Intense pain in the joint
  • Joint redness and swelling
  • Chills and fever
  • Inability to move the area with the infected joint

One type of infectious arthritis is reactive arthritis. The reaction is to an infection somewhere else in your body. The joint is usually the knee, ankle, or toe. Sometimes, reactive arthritis is set off by an infection in the bladder, or in the urethra, which carries urine out of the body. In women, an infection in the vagina can cause the reaction. For both men and women, it can start with bacteria passed on during sex. Another form of reactive arthritis starts with eating food or handling something that has bacteria on it.

To diagnose infectious arthritis, your health care provider may do tests of your blood, urine, and joint fluid. Treatment includes medicines and sometimes surgery.

  • Fungal arthritis
  • HLA-B27 antigen
  • Reactive arthritis
  • Septic arthritis
  • Viral arthritis

Lyme Disease

Lyme disease is a bacterial infection you get from the bite of an infected tick. The first symptom is usually a rash, which may look like a bull's eye. As the infection spreads, you may have

  • A fever
  • A headache
  • Muscle and joint aches
  • A stiff neck
  • Fatigue

Lyme disease can be hard to diagnose because you may not have noticed a tick bite. Also, many of its symptoms are like those of the flu and other diseases. In the early stages, your health care provider will look at your symptoms and medical history, to figure out whether you have Lyme disease. Lab tests may help at this stage, but may not always give a clear answer. In the later stages of the disease, a different lab test can confirm whether you have it.

Antibiotics can cure most cases of Lyme disease. The sooner treatment begins, the quicker and more complete the recovery.

After treatment, some patients may still have muscle or joint aches and nervous system symptoms. This is called post-Lyme disease syndrome (PLDS). Long-term antibiotics have not been shown to help with PLDS. However, there are ways to help with the symptoms of PLDS, and most patients do get better with time.
