Amy do you have a primary care doctor?  If so you may need to go in and see him.   Have you started on your B12 yet?  Keep after your doctor and don't let him brush you off.  You are paying him, you are the boss.  I have never had this problem.  Hope you get some relief soon.

Yes I'm seeing my primary doctor tomorrow. I've been seeing him about twice a week for 2 weeks trying to get my potassium squared away, it's coming along. I have started my B12 as well as all my other vitamins. Thanks for responding, I'm losing my mind. Not to mention my potassium problem has reversed my metabolism and I haven't lost any weight in over a week. UGH

Hello,
I have not had surgery yet but I have had pinched nerves. It can feel like the sensation you describe. Still follow thru with your primary doc.

   Google side effects of Effexor and you'll see that it may be caused by that.   When I was reading this, I remembered an online friend of mine mentioning that she had issues with tingling like that, and she is also on Effexor.

Restless Leg Syndrome actually CAN affect other parts of the body, even the whole body. But that doesn't sound like what you describe. How old are you? Any chance you could be starting menopause? There's something that sometimes happens in menopause that feels like ants crawling on you---it's called formication.

I'm 27 I sure hope I'm not going into menopause I 'd like to have a baby first.

I think you can rule menopause out Sweetie!!

I am diabetic and live with this.  It keeps me awake at night.  I take neurontin for this at night.
