How To Treat Low BP?

Greeting! My name is Gabriela, last year i was diagnosed with NCS. Altough I don t faint, everytime my blood pressure drops to sys 78/dia 48 BP 55, feels like dying. Altough, there is a symptom that worries me, sometimes with a crisis, i feel the legs a little unresponsive, and I have the same sensation with my arms, mostly the right arm, feels like is not there, and I move it counscionsly to reasure myself is there and functioning. Like numbness. Is this symptom part of the dysautonomia? 70 kg, 1.67 m, 32 years old.
