Hey Mokeyho,
I am so glad you are treating the lyme first. You have so many more lyme symptoms than MS. Sore throat and fever and the other signs of infection just don't make sense in MS.
I know that testing for MS and or Lyme can be confusing and frustrating. Paying close attention to those symptoms is really important. I am quite sure I don't have lyme based solely on my symptoms. I don't have those classic signs of infection. I am very very stable day to day. I have almost no fluctuation of symptoms. I don't have fevers or achey joints. I don't flare on a monthly basis. I never feel worse after a routine course of antibiotics (say for a sinus infection). I have a consistently hight energy level. I have zero swelling. I have not had an increase of symptoms or lesions for over two years. And while I do have MS issues I deal with everyday. I work full time; I am a wife and a mom. I live with very few limits so far. I hate to say it, but chronic lyme is much worse than what I deal with! I may feel differently several years down the line, but for know I will count my blessings.
MS moves slowly. After the first few years, MS tends to slow down for a long time. You may only flare once a year or once every couple of years. Although, everyone progresses differently.
I agree that lyme may be one of the causes of MS. I don't believe it is the only cause.
I hope this helps someone to manage their disease, whatever that may be. I continue to stand by my orignial opinion that when in doubt, you treat for lyme first. Your response to that treatment could help to verify your dx.
