I'm new around here and would like to hear people's opinions on my symptoms. I had an MRI that showed some lesions that my nuero said didn't look exactly like MS lesions, but he was very vague and didn't rule it out. Then I had a spinal tap to check for signs of MS. Here are my results: No oligoclonal bands detected (negative), Myelin Basic Protein <2.0ug/L (negative), and a negative IgG synthesis rate, as well. All negative results and my nuero declared that I didn't have MS. However, I still have these undefined lesions and some symptoms. Here are some symptoms: positive ANA, stiff back and knees, lower back pain, eye floaters, bladder urgency, foggy thinking, some tremor of my left arm when i pull down on something, and the left side of my face went somewhat numb and tingled recently.
My main question is this: is a negative result from my spinal fluid enough to rule out MS? Or is it at least unlikely that I would have MS considering the negative spinal fluid result? Do I need a second opinion, or are MS type lesions very well defined and characteristic (i.e. - my nuero would know for sure if they were MS lesions?)?
Just as an aside, I am also being tested for Lyme, as this seems to explain some of my symptoms. Any info is greatly appreciated. Thanks.
