My daughter had a spell while driving yesterday that made her pull off the road.  She said her face was tingling and then it went to her arms and stomach.  She said it felt like when your arm falls asleep but it was her upper body.  She said it was also hard to swallow and she felt like her face was droopy.  Someone told her that her blood pressure had bottomed out.  Is this true and isnt that dangerous?
Yes all these findings may be due to high BP or low BP...but most probably she had high BP...please get her to emergency as deranged BP may cause some other problems .sudden rise in BP may cause such symptoms and second possibility is that your child is having cervical strain ...so please go to ER...there should be BP check up ...her ECG and cervical spine X-ray
