Two things. First, what is MS? It just means multiple sclerosis or many scars. To say that a lesion on your brain is lyme and a lesion on your spine is MS is ridiculous. It's like saying a scar on my face is different than a scar on my leg! Here's the difference. In the brain there is more room, it's more elastic so if you have a lesion and stop the infection(which I believe is the cause of these lesions)the blood can flow around the lesion and it's capable of healing just like getting stitches, the wound heals and over time the scar fades away and gets lighter. So, you have a scar on your face, or in your brain but there is more room to heal. In the spine, the nerves are compressed a lot tighter together to fit in the spinal canal, so there is less room for blood to flow around and remyelinate or heal. So, if you get a lesion on your spine it's going to affect your walking and use of your limbs. I suppose that my definition of MS was just that, losing your functionality with your limbs. When my cousin was so fatigued, massive headache, raging, anxious I said to myself something wasn't right, this isn't MS as I thought it to be and the rest is history, I discovered Lyme, Bartonella, and Babesia and damned if I wasn't right. Truthfully it was the easiest diagnosis ever, but the hardest 27 months of our lives. The MS doctors still insist he has MS despite a plethora of positive test. There is no MS test and an LP does not provide any definite information. Fortunately, my cousin had lesions in his brain and just a small one in his spine. He is much better, but still not great yet! My point is that a lesion is a lesion there are better places to have them that are easier to heal but saying one is MS and one is lyme is quite honestly silly. It's my opinion that MS is infection related and Lyme is involved. There is also a growing amount of science pointing that direction.
