on of my legs feels different

Bones, joints and muscles

so for the past little while right eg feels different than the other, i dont know how to describe the sensation, i dont walk differently because of it. there is no tingling or numbness ever in that leg unless i sit on it incorrectly. 

then when i lay down at night its almost as if when i breathe in there is a sensation pulsing through my right leg, Not painful and not numb or tinglaing again just annoying

Should i be concerned?

Is it cramps that you are experiencing?  I get them in both my legs now and then.

not so much cramps, it doesnt hurt

I hope someone here may have some idea as to what it is.
