Here’s what to know about Lyme disease
Lyme disease is caused by bacteria transmitted through the bite of infected deer ticks. Early symptoms include fatigue, fever, headache, and joint pain. If not diagnosed early, it can lead to more serious health issues, including neurological problems and severe arthritis.
Most cases of Lyme disease are treatable with antibiotics, but recovery can take time. Some individuals experience lingering symptoms even after treatment. According to the Centers for Disease Control and Prevention (CDC), about 476,000 people are treated for Lyme disease in the United States each year, based on insurance records.
Timberlake ended his Instagram post by thanking his wife, actress Jessica Biel, and their two sons, Silas and Phin. “Nothing is more powerful than your unconditional love,” he wrote. “You are my heart and my home. I’m on my way.”
