My doctor had me to a nerve test with the needles to see if i still had a pinched nerve...the reason this was done is because whenever i pick up something and stand with correct posture, I loose feeling below my knees! Feels like im a big sack of tattas thats about ready to fall on the floor! I have noticed it is only when im holding something 5-10+ lbs and"dont forget" standing the right way...full up,not hunched over... I am concerned cause if its not a nerve can it be ever fixed? Could it be my low blood pressure? confused...Feels like im just falling apart. Have not talked much with my doctor about it cause i don't wanna feel like a hypochondriac more than i already am. Thanks all and anyone for any help or suggestions given!
