I can relate to the feelings on your leg. Its called "altered sensation". Its not really numb but feels numbish. I likened it to feeling like I was wearing a rubber glove or something. I could feel, but the feeling wasn't correct.

As for the other things, I can not relate. Might be wise for you to keep a detailed journal of how you feel so you can judge time and space.

Just keep hanging in there and try not to get too discouraged. If there is something wrong, it could take a long time before the moon and the stars line-up just right.......and you find out what it is!
