I agree with many here about the Plaq. I'm on it with biaxin and haven't had any trouble. Went to the eye doc who was surprisingly informed re: the plaq and Lyme. He was more worried about what Lyme would do to my eyes then the plaq. So I felt much better! By the way, he started me on "Soothe" eye drops. You can get them anywhere and they really help the eye burning and achiness.
Yes, the tongue thing is probably yeast. You need to get a good Lyme book that talks about how to keep that at bay. "Everything you need to know about lyme", "coping with lyme disease", even "chronic fatigue, fibromyalgia, and lyme disease; 2nd" are very useful and probably at your local library. But you need to start with the "sugar busters" diet; no sugars, very low carbs. Yeast thrive in a high sugar environment! Also you should be taking some sort of acidopholis.
I know the pain really sucks! I used to get really confused trying to figure out what was Lyme pain and what pain was from meds. Then I had a whole body herx and wanted to die.
Try to trust your LLMD. My LLMD will do phone appt also, but she will answer email questions without charge. See if your's will.
Hope this helps!
