7 Sneaky Signs of Lyme Disease

Know the symptoms so you can stay safe.

We've all know the warning to beware of ticks and Lyme disease in the summer. But how much do you really know about it? The more you understand about the bugs and the seriousness of the disease they can spread, the better you can protect yourself. Here's what to know about contracting Lyme disease and seven little-known signs you have it.

Lyme disease experts, John Aucott, M.D., of Johns Hopkins University School of Medicine, director of Johns Hopkins Lyme Disease Clinical Research Center, and Gary Wormser, M.D., of New York Medical College, founder of Lyme Disease Diagnostic Center share what you need to know to safe.


Lyme disease cases increase in the summer because people are outside more in places like forests or grassy areas where there are deer ticks, which carry the bacterium Borrelia burgdorferi. You could get bitten by a tick while outside, or it could latch onto your dog and jump to you later.

Lyme disease can only live inside a host animal and is transmitted from animal to animal by the bite of a tick. Even if you removed an infected tick soon after a bite, you could still get Lyme disease.


“Within seven to 14 days after removal of an infected tick, an enlarged—at least two inches in diameter—skin infection or rash will develop at the tick bite site if that tick has transmitted Borrelia burgdorferi (the Lyme disease bacterium)," says Dr. Wormser. This rash is called “erythema migrans." “It's important that any individual with tick exposure look once daily at the entire skin surface to see if a rash has developed for 30 days," Dr. Wormser adds. The rash might like a bull's eye but only about 30 percent of rashes look like that. “The rashes are usually uniformly red or bluish-red and round but they don't have that ring within a ring appearance," says Dr. Aucott.

Be on the lookout for a fever or a headache if a tick bit you. It's an early sign that you might have contracted Lyme disease. Take your temperature daily while continuing to look out for that telltale rash.

Body Aches

Feeling achy joints and body aches are early symptoms of Lyme disease. Joint pain often comes early on along with the rash, says Dr. Wormser.


Experiencing chills during hot summer months might indicate that you've been infected with Lyme disease. It's one of the flu-like symptoms, like fever, body aches, and headaches that are a symptom of the early stages of Lyme disease.

Sure, you could blame the heat or a busy summer schedule, but feeling fatigued is a sign that the tick you pulled off might have infected you with Lyme disease. “Sometimes these symptoms aren't recognized by the patient because they're too mild and they don't experience any symptoms," warns Dr. Aucott.

Facial Paralysis

When one side of the face is drooping, it could mean a number of things, from a stroke to Bell's palsy, or a symptom of Lyme disease. People with facial palsy caused by Lyme disease may not have other symptoms.Make an appointment to see your doctor right away. Lyme disease will need to be confirmed with a blood test. In phase one you'll feel achy and like you have a summer flu, says Dr. Aucott. This is within the first few weeks. If you don't get treatment for Lyme disease, phase two can develop into meningitis, hepatitis, Bell's palsy, and an irregular heartbeat in weeks four through eight after the bite.

Joint Swelling

“Arthritis, i.e. joint swelling, can occur up to six months after the bite, but may develop sooner, and even up to two years later," says Dr. Wormser. “Lyme arthritis is considered a late manifestation of Lyme disease." This last phase of untreated Lyme disease also includes joint numbness, adds Dr. Aucott.

If you think you might have Lyme disease based on your symptoms, make an appointment with your doctor right away. He or she will administer a simple blood test that can confirm whether you have this disease, says Dr. Wormser. “The blood test doesn't turn positive for three to four weeks," says Dr. Aucott. “At the earliest stage (week one and two), the blood test is usually negative." Keep in mind that not everyone with these symptoms who tests positive for Lyme disease has the disease; it might be from a prior asymptomatic infection, says Dr. Wormser.


Dr. Wormser advises patients to do the following to help prevent getting Lyme disease: First, cover up exposed skin before going out hiking or into a wooded area. Then, apply a tick repellant to exposed skin (except your hands and face). When you come home, do a skin tick check at least daily. Check your pets for ticks after being outside and put the clothes you wore in the dryer on a hot cycle for at least 10 minutes.

When Dr. Oz found out in September 2019 that his mom, Suna, then 81, was diagnosed with Alzheimer's disease, he was gutted. He wondered how he missed the signs and what he could do next. Like so many caregivers, he had to recognize that his mom was not going to get better. But he also knew that he wasn't alone: There is an Alzheimer's diagnosis every 65 seconds.

Dr. Oz immediately contacted his friends and colleagues and crafted a treatment plan with two of the country's top experts in the field: Richard S. Isaacson, MD, a neurologist at NewYork-Presbyterian/Weill Cornell Medical Center and the founder of the Alzheimer's Prevention Clinic, and Dr. Rudy Tanzi, a professor of neurology at Harvard and the founder of the "Alzheimer's Genome Project," who co-discovered the first Alzheimer's gene.
