Hey Carolyn,
I am glad to hear from you but so sad that you are still having problems and that those problems are getting worse.
I would not go to the ER unless you wake up with significant vision loss. For MS (and I know you don't have a dx) the rule of thumb i you only go to the ER when you can't care for yourself. Obviously that would include unmanageable pain, vision loss, paralysis or anything else that keeps you bedbound.
How is your lyme treatment going? I know that that diagnosis was complicating things. Which came first the chicken/lyme of the egg/MS. Hehehe.
Seriously though, I hope you are feeling better very soon. Please let us know what is going on. I can't remember what MS tests you have had. Please remind me of your MRIs lumbar punctures and junk............just curious.
