Thank you for your query on Healthcare Magic.
It seems you developed hyperventilation
because of climbing to high altitude of 9000 feet.
Hyperventilation leads to wash out of carbon dioxide from body which in turn cause low calcium in the blood.
Low calcium causes these symptoms of tingling
, locked and cramped hands with slurring of speech.
I suggest you to breath normally and if you develop these symptoms again, you can use a bad into which you can breathe in and out and this should be done after knowing the complete procedure with the help of your physician.
Hope I have answered your query.
