Has anyone had to face the problem of restless legs or restless leg syndrome after doing LL?

The reason I'm asking this is, I've been stretching a lot off late to prepare for my LL surgery, but I notice that ever since I started stretching, I've been getting this tingling sensation in my legs (mostly my right) when I try to sleep at night.

I'm afraid because if this is happening when I stretch my legs for a minute or two per day, what could happen when they are permanently stretched 5-6 cms after LL? :O

LL veterans, please advise.
