Hi Elissa,
Welcome to our community!! I'm so glad that you have found this to be a wonderful place - we kind of like it too!
If you haven't already, it would be helpful for you to start with reading through the thread at the top of the forum titled,
"New to Lyme?...Start here!!" (even though you aren't really "new" to Lyme!), as it is packed full of important information, symptom lists (as Lyme rarely occurs by itself), helpful links and pdf's, how to detox when one has these infections, and a list of questions that you can ask any doctor that you are seeking treatment from.
The new recommendations (just came out) from ILADS (International Lyme and Associate Diseases Society) is that all new tick attachments and suspected Lyme cases be treated with 100- 200 mgs of Doxy, twice a day for 20 days.

Although you told us you spend weekend on Long Island, I'm not sure where you spend the rest of the week, which is likely where you would like to have a LLMD (trained by ILADS). Could you send me an email and I can likely help you find one in whichever area is best? You can send me an email by clicking on my screen name or on the little blue envelope under my name. Please include the area that you hope to find a LLMD.
