May is National Lyme Disease Awareness Month. Lyme disease is the most common vector-borne illness in the United States. It is transmitted by the bite of a tick that is infected with bacterium. The disease can cause fatigue, fever, headache, and rash, and can affect our joints, heart, and nervous system. But did you know that Lyme disease can also affect your ears? Lyme disease may cause hearing loss, tinnitus, vertigo, and sound sensitivity. Although the disease can sometimes be treated successfully with antibiotics, prevention is key. This may include using insect repellent and removing ticks from the body promptly.
