Sorry -- I need to complain

My left leg hurts....it is bringing me to tears and I have no idea what it is.
For the past 6 weeks or so I get "numbness" in the top of my thighs, right in the front where they connect to the rest of my body. It sucks, MFM said it's just my nerves and nothing they can do.
The pain started this morning. I was getting out of the shower and my left leg hurt bad -- I yelled out in pain as I stepped out of the shower. It is just one spot in the front area (same as numbness) that gets sharp pains. It feels like I have a string in my leg, all twisted up and someone has pulled really fast and hard and straightened out the twist. I hope that makes sense.
So it happened this morning getting out of the shower, and now twice while sitting on the couch just bending forward. I have an appointment on Wednesday with the MFM and I'll bring it up but has this happened to anyone else? I feel like such a wimp because I cry when it happens but darn, it HURTS.
Re: Ouch, ouch, ouch
Ug -- it just happened again and I screamed and yelled so loud DH came running to see if I fell or something. Holy cow.....
If these are cramps they are the weirdest cramps I've ever felt. They are like bolts of lightening in my leg and then they are gone with just light stinging left.
I will have to look into the chiro -- my upper back has been hurting lately so I probalby need to go anyway. Thank you for that suggestion!
