Thank you all who left comments and emailed me. It really does help knowing that there are friends out there thinking of us and praying for us.
We go the results of the MRI today, everything looks normal. No tumors, no structural abnormalities. The lab tests for the more rare things the doctor wanted to check for were not back yet, but he feels confident that there isn't an underlying disease.
He prescribed a drug used for neurological pain to see if it will stop the thrashing and hopefully I will be able to sleep. I'll let y'all know if it works AFTER I WAKE UP!!! Keep your fingers crossed for us.
And thank you again for your friendships and supportive words.
