Chronic Lyme disease is a controversial topic in the medical community, with some doctors arguing it doesn't exist. Those who believe in the condition may use different terms to describe it, such as post-treatment Lyme disease syndrome or persistent Lyme disease. Other possible synonyms include late-stage Lyme disease or chronic borreliosis. Patients may also refer to the condition as chronic Lyme borreliosis or simply chronic Lyme. Regardless of the preferred terminology, the symptoms of chronic Lyme disease typically include fatigue, joint pain, and cognitive impairment. Treatment can be challenging, with many patients requiring long-term antibiotics and alternative therapies to manage their symptoms.
