Hello there, and I am so sorry that you are having such a rough time.
May I suggest that you look at all the side effects of your meds and see if any of the symptoms your having could be caused by your meds.
Some of these symptoms are produced by the anxiety and with your situation without insurance I can see why you would be even more anxious.
A visit to a neurologist may be in your future but does not mean necessarily that you need a lot more tests.
You have my support and understanding so please keep posting.
You are family here. (((((((((((HUGS))))))))))))
