Weak leg again

[pb]

If i kneel on my leg it feels weak - usually just lasts for a short while.
I know that its probably nothing serious- but i still keep thinking mnd !!!

I get this too and weakness in my legs while walking. Though I think nothing of it, as this is due to anxiety and feeling on edge for me. Does it happen randomly or are you very anxious at the time?
