Yesterday, at 3 pm, both of my kegs from my knee to my feet suddenly turned into jelly whiles I was in the bathroom. I tried To stand, but could not. I fell to the floor and lad there for about 20 minutes before I was able to stand and have a shower. I am 53, post menopausal and suffer from high blood pressure, obesity and under active thyroid. I also take anti-depressants. I want to know the possible reason for my collapse. I Felt no pain, just complete numbness of my lower limbs.
