According to the Centers for Disease Control, at least 300,000 people in the U.S. will contract Lyme disease this year, the vast majority in the east and Midwest of the country. Yet many, like pop star Avril Lavigne, will be misdiagnosed and told to get some rest or even seek psychiatric care. The reason is because symptoms of Lyme are often vague, insidious and similar to those presented by other, often less serious, maladies. After a tick bite, proof of which is only sometimes visible as a ‘bull’s eye rash,’ Lyme sufferers develop flu-like symptoms. Weeks later, neurological and rheumatological symptoms set in—such as brain fog, headaches, shooting pains and sore joints. Lavigne finally got proper antibiotic treatment by consulting a Lyme specialist, so don’t be afraid to do the same if your general physician dismisses your complaints without doing specific blood tests. She’s doing well, and you can, too.
