Oh PP901,
Don't let us scare you!! There is no way of knowing what or how severe things will get for anyone! This is just a discussion of some things that others have found that help.
So you are in treatment already, good! Have you read through our "New to Lyme? Start here!" thread that sits at the top of the forum? Even though you aren't 'new to Lyme', there is so much good information in that thread, it would be worth your time to go through it.
Are you taking any B-12 supplements of any type? You will want to be sure that they are of the Methyl -type of B-12, not the Cyano-type as the body has to convert the Cyano-type to the Methyl-type before the body can use it.
Time in treatment will do wonders for all types of symptoms of course, but will detoxing. Are you currently on a detoxing schedule? Detoxing is also covered in our "New to Lyme?" thread.
I'm sure we can help you get through these rough times here!! We have a great community here that is incredibly supportive and helpful to all!
