Weird Numbness

So, I have a tickle on my left shoulder...doesn't itch, feels like a bug crawling in a circle...then my tongue went numb a week later, then my foot went numb now my left arm...It's totally freaking me out. Nothing hurts. I wonder if it could be from holding the kids as I do it on my left hip. But again, no pain in my back/neck area. I see my GP on Tuesday morning and will probably get sent to a neuro...fingers crossed it's nothing serious!
