It is very important to see a knowledgeable doctor. Infectious disease are often not the best to see unless they specialize in tick-borne illnesses. Besides Lyme, ticks can also transmit several co-infections including Babesiosis, two types of Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. Many people who have Lyme are co-infected. It may affect treatment choice and progress. It is important to be tested for these by a Lyme reputable lab such as IgeneX in Palo Alto, CA. Have you been tested for these?
What are the initials of the doctor you will be seeing? You can email me at email@example.com for doctor recommendations.
200 mg of Doxy is not strong enough for Lyme. I believe the recommended dose for Lyme is 300-600 mg daily. There are some important tips to know about taking Doxy. Do not have any dairy, iron, or magnesium products within two hours or it will not be absorbed properly. If it makes you nauseous, eat something substantial and non-dairy before taking it. Avoid the sun. You can get a severe burn in minutes even when wearing sunscreen. Do not lay down for at least an hour after taking it or you can ulcertate your esophagus. This is very painful. Drink a full glass of water when you take it for the same reason. Whenever you take antibiotics, make sure you take high-quality acidophilus capsules at least two hours apart from the antibiotics. The best ones to get are refrigerated and have a high culture count. Most healthfood stores have them.
During treatment, it is important to document your symptoms daily. One way to do this is to list the three main symptoms you have each day with a numerical rating of their severity from 1-10. Over time when you review this, you can see when your herxes occur and how you are responding to the meds.
It is also important to learn as much as possible. I recommend reading Dr. Joseph Burrascano's 2005 Diagnostic Hints and Treatment Guidelines For Lyme and Other Tick Borne Illnesses at http://www.ilads.org/burrascano_0905.html He is one of the top Lyme doctors in the country, and many Lyme doctors follow his protocols. He also lists diet, supplement, and exercise recommendations. I also recommend the books "Everything You Need To Know about Lyme Disease Second Edition" by Karen Vanderhoof-Forschner and "The Lyme Disease Solution" by Kenneth B. Singelton MD.
