I had an MRI of my lumbar spine recently and it showed that I also have three bulging discs and a Tarlov cyst. I am having difficulty walking for more than 30 minutes, my back gets stiff and burns, it feels like it is going to break in two. I also have a problem standing for more than 10 minutes. I am in a quandry as to whether it is the Lyme or the other problems, I am thinking a combo of both. Thanks all for your input.
