After tilt table testing I was diagnosed w neuromediated hypotension w vaso vagel response and left bundle branch block. Basically I ve always fainted with dental or medical procedures or when under extreme stress. Also sudden fear causes my hands to go numb and tingly. If I have 1-2 drinks w alcohol I get the same sensation of numbness and to tingling in my hands. The other day I had a syncope episode after getting lidocane injections for back pain. After the syncope episode the doctors were monitoring my blood pressure bc it was very low and I was having the numbness in my hands for about 2O minutes. What causes the numbness and tingling sensation in these instances. Is it anything to worry about or a sign of underlying condition?
