What Causes Numbness In My Arm, Neck And Roof Of Mouth And Tongue?

About an hour after a tumbling class my 14 yr old daughter experienced right arm numbness, numbness in the front of her neck, numbness in the roof of mouth and tounge, confused speech (no slurring, only lasted about 15 minutes). After about an an hour of these symptoms she experienced light sensativity and a really bad headache. ER doctors said it was a migraine. This has happen 2 additional times over the last 2 weeks. They all happened after a tumbling class but she has also gone to tumbling and nothing has happened over the last 2 weeks. This just seems strange. Any advise as to what this could be?
