Hello, My Name Is Kristen. I Am A 27 Year

Hello, My name is Kristen.
I am a 27 year old healthy female. I have been experiencing sensitivity and pain in my left leg. It comes and goes. The slightest touch hurts, It is also sensitive to cold. The pain is not terrible, but quite annoying. It changes areas too and is not always the same area, Right now the back of my calve and under my buttocks on the left side is the most sensitive. It is only in the left side. It has been coming and going for about a month now.
