Emily, He went off my medical records, exposure, when I began to get sick, looked at everything I been dx with since 97. He even said that he has one other case in his office just like mine. That she has POTS, and even had the ablation, pacemaker, and that, we both even have sphincter of oddi dx. As for the blood test again he said the fact that I been on doxy for 5 months now, and that I am just getting over the blood infection with all the IV abx that I am going to show a negative test. He also went off how bad of a herx I had while on the doxy, and that then I improved, and that it leveled off, (I guess with all this it was enough for him) It was a 3 ? hour appointment he listen, and asked so many questions, and wanted the dates, and what health conditions happen first. So the lyme?s for me started in the autonomic nervous system, and then moved to the nervous system from my understanding. I was overwhelmed with all the information. I am still learning all about this, my understanding from the appointment, the longer you have it, and the move damage done the harder it is going to be to treat. I am really worried about a Herx on the IV abx, as with the blood infection I had I had the worst headaches, and I was in the hospital so the where able to give me extra fluids, and pain meds. Now I am going to be at home on the IV meds. Have you been on IV abx? If so how did it go? What are your thoughts about IV abx? I am really worried about everything right now, and I hope the treatment will work, but I don?t want to put all my hope in it and get depressed you know. This summer when I was told I had Lyme?s and started treatment I thought finally?.. and things didn?t get better like I thought they would. I am hoping that now under the care of a LLMD that I will get a treatment that will improve my quality of life. I would love to go back to work one day?.. but if not just be able to keep up with my son!
