Lyme disease is an infection caused by the bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected blacklegged ticks. While Lyme disease can affect various organs and systems in the body, the most common symptom is a characteristic rash, called erythema migrans.
When it comes to joint involvement, Lyme disease can cause a type of arthritis known as Lyme arthritis, which typically affects one or a few large joints, most commonly the knee. The other joints that can be affected by Lyme disease include the hip, shoulder, elbow, wrist, and ankle. Lyme arthritis usually develops several weeks to a few months after the onset of infection and may last for several months or longer if left untreated.
In some cases, Lyme disease can also cause neurological symptoms, such as meningitis or encephalitis, which can lead to muscle weakness and joint pain. It is important to seek medical attention promptly if you suspect that you may have Lyme disease, as early diagnosis and treatment can help prevent long-term complications.
