I had a severe migraine a couple days ago. I get them periodically and my hands and feet tense up, This last migraine the left right side of my face, lips, and tongue went numb and tingley. Also both feet went numb. The symptoms usually are worse on the right side of my body. The migraine is gone but my right arm from shoulder to finger tips is still really tense and twitchey? What could this be and why has it not subsided like usual?
