Sounds like you have a good doctor sorry it is taking so long to find an answer. There is no magic in medicine unfortunately. It took me 46 years to figure out I had MS and 4 to figure out I had Cancer which was worse since the Cancer was spreading. I had good Doctors looking for things they just could not figure it out. Hopefully you will get an answer soon. My MS took a long time because I started with PPMS as a child and it progressed slowly. It just did not fit the typical MS. Back in the 1960's they did not know children could get MS. They also did not have MRIs. I still only have three or four lesions. My LP was off the charts so I was finally diagnosed with that.

Balance issues, memory problems, getting lost, meniere's, pins & needles, muscle pain, dizzyness, nausea, abdominal pain, and demyelinating lesions can all be symptoms of Lyme Disease. With leg pain, abdominal pain, and lots of neuro symptoms, you are a really good candidate for a coinfection called Bartonella, too.
You are in Lyme country, so you'll want to get checked out for Lyme Disease before you take any immune suppressing drugs. They make an infection much worse. Standard blood tests produce way too many false negatives, so a negative does not exclude it. My Lyme mimiced MS, including the numerous brain lesions in my white matter. I also have Bartonella. I had most of the symptoms you describe.
You are welcome to come tell us your symptoms and progression on the Lyme Disease forum and see what others think. We have some wonderfully supportive and knowledgeable people there, too. (The folks here are awesome!)
I know you are frustrated and want an answer. Perhaps seeing a MS Specialist would help. Many Neurologists follow you a long time especially if you do not have MS lesions on a MRI or a Lumbar Puncture with evidence of MS. It took me two years and the positive Lumbar Puncture before I was finally diagnosed and tons of blood work to rule out anything else. I had 5 positive MRIs. The insurance companies want the doctors to be very sure before they can give you the MS medications. MS medications are have a lot of side effects and are thousands of dollars a month so they want to be sure. I am sorry you are going through this.
