I am a blood pressure person, during my last flight while landing i started feeling dizzy & unconscious then afterwards i had a sort of paralysis attack? what precautions should i take?

Check blood pressure: If it were possible it would have been most helpful to know what your blood pressure and pulse rate were at the time of symptoms. The dizziness and faintlike symptoms could have been due to too low a bp, too high a bp, too low a pulse rate or too high a pulse rate. Make sure you're taking the proper doses of medication before taking your flight. It appears you had no damage during your episode.
