Is this a symptom of peri-menopause?

So, I have been experiencing an odd feeling the last couple of days. It feels as though a bug is crawling across my right shin. I go to brush it away and there is nothing there. I am not crazy..

I am 39, and have had odd periods (light flow, last only a few days, and they’re erratic (never happen at the same time each month).

My Mom had a full hysterectomy at 38. My sister went through peri-menopause at 37.

I read online (at some health forum) that it is called Formication. Anyone heard of this? Is this a symptom of peri-menopause?
