hi,anyone ever had this? it started last night,it was like `something gives me the creeps" but in my legs lol i would have this cooling feeling or maybe slightly burning in some parts of my legs. and the "creeps"were going upwards.since than my legs feel achey,more in the back,and i think it`s kind of a dull ache but i can`t really describe it,or actually anything ...have anyone felt anything similar? it drives me nuts..
