Hi,
I can tell you that my exacerbations have been spaced similarly. I know that I was under a load of stress each time one came on. My first was only Ocular Neuritis, the second was full-out weakness, tingling, etc. The tingling in my feet came first that time and this current time.
I am about to start Betaseron therapy (this week) and am terrified of the needles. I received the autoject device which is even scarier to me.
Alternately, I see an acupuncturist weekly and asked him about chelation. He said it is very contraversial and he would not recommend it. His reason was that chelation frees up the stored metals that are in your body, such as Mercury. When it is freed by this process, it is unclear as to how it is redistributed, and if it is cleansed or not. Especially when done with oral medicines. Proper chelation is done in the hospital by a doctor. I would definately discuss your thoughts about chelation with your neuro first. Do not self prescribe!!
I have found that juicing (vegetables) daily really helps me. Also, eliminating sugars and other stimulants really helps my energy level and ability to focus. My symptoms, gratefully are very minimal. I am hoping the Betaseron will help keep it that way.
Best luck to you.
Ginni
