I had a major panic attack after being sent to another country for a week for work, when i arrived at the airport i started cryong and violently shaking, my legs coyldnt move, feet were dead, right lower lip was shaking and pulling into a spasm, dizzy and disorientated, the flying for the first time and being away from home was just too much, when my husband saw me he said it looked like i was having a stroke, my whole face was scew
i'm sorry to hear this 
its really tough.. im almost going through the same kind of sensations... visit a psycatrist asap and get your medications and therapies... start trying some yoga, exercise.. and relaxing music .. Hope you are back to normal soon.

You sound like you are back home now ??
Talk to your GP. However it sounds like you were stressed out due to the flight and fear of flying.
If you feel or it looks like you may have suffere an minor stroke you should see your GP.
The body can in some instances suffer problems associated with the altitude
Your GP will put your mind at rest
