i have unexplained acute onset of tingling in both my legs nerve test shows no problem?
from your history i don’t think that there is something clear enough can diagnose a specific case tingling in the arms goes away by changing position is nothing serious then vitamin b deficiency. the old tingling you have been suffering from yes almost caused by hypertension and i recommend doing lipid profile analysis to test 4 arterial changes you can also try doing an x-ray of the cervical region
