Michelle - please go to a doctor TODAY. Hopefully a competent doctor, but a doctor, and do not leave until they take action. It may be something simple like low blood iron but you can't carry on if you are also afraid to go to sleep.
Also - when all these current crises are past, I think you should get reassessed about all the different meds you are taking. There are lots of risks/side effects from long term use of BP and cholesterol medications. The docs are pretty quick to hand these out when they may not be necessary and there may be other things you can do to manage blood pressure and cholesterol.
As someone else said, it seems unlikely to be spinal cord because your upper and lower limbs are involved. That would require pressure/damage in your neck region.
I'll bet the numb foot is linked and, obviously, you can't rule out MS because of your sisters. However, I didn't think MS started in such an extreme way. Your sisters should know all about it and can give you advice.
Big hugs to you,
sister. You are very important to us. Hie thee to a doctor quick as you can.
love and hugs
