I'm glad that MS was ruled out for now. Lyme isn't anything to play around with so I hope your doctor can help you.
Even though you're not suspecting MS it would be a good idea to keep a journal or log of your daily symptoms and the medications you take. That will prove to be invaluable to your doctor when trying to make sense of your symptoms.
I hope you'll still continue to visit this forum. Lots of our members don't have an MS diagnosis yet but continue to have symptoms. You're welcome here anytime.
