Hi Sarah, I wanted to welcome you to the site. I am glad you took the time to find it. There are more of the most amazing, generous and helpful people here then anywhere I have physically gone. I have received an incredible amount of emotional help as well as more education and referrals than ANY single MD has given me.
It sounds to me that you need to see a neurologist and that you are already waiting to see one. But meanwhile, look around here; search other post for similar symptoms and maybe you'll get some respones back as well that will be helpful.
I am very sympathetic to what you are going through- it must be wretched especially with a new baby and other children - my thoughts are with you!
