Hi Sunny, Welcome to our side of the world.
It sounds like you have enough going against you. I sure hope you don't have to add MS to the mix..
Your Symptoms could be due to MS, but they could also be due to any number of neurological illnesses.
Please come back and let us know what your Neuro says and in the meantime, stretch those leg muscles. I find that if I can't lift my leg, it's because I have been in one position for too long and a little mild stretching helps a lot.
I hope you feel better soon..
