Concerned you may have Lyme disease or want to get tested for Lyme disease? Lyme disease is transmitted via an infected tick’s bite and bacteria, causing extreme exhaustion, achy muscles, chills/fever, headaches, and sometimes a rash. If you believe you may have been infected or come into contact with any of these symptoms after spending time outdoors, it’s essential that you get tested as soon as possible. Lyme disease has some potentially harmful long-term effects if not treated right away. Come to our office in Jacksonville for discrete testing and treatment options customized specifically for YOU.
