By any chance did your work up include a CT of brain or an MRI of brain? I recently had a stroke and thought it was an ocular migraine so didn't go to the hospital until the following day. My right arm and leg were completely useless. They did the CT scan which showed no bleeding, but the MRI did show an acute thalamic stroke. Part of my work up now is to have a 2-week EKG to be sure I don't have a heart problem causing this. I would suggest you ask your doctor a few more questions and also ask for a copy of your records. Please find out more information for your own heath and safety sake. All the best to you.
