Numb arms and legs, getting worse everyday?

okay, here is a weird problem for you. If anyone has advice on what I should do, please let me know. I am a 20 year old female and I have been having a numb problem. One day, about a year ago, I woke up with a claw hand. My hang literally looked like a claw and it took about ten seconds of me moving it for it to return back to normal. It kept happening every night until one day I woke up and it was the other hand doing it. This freaked me out a little but I dealt with it because I do not have health insurance. As months went on, its been getting worse. My legs also go numb throughout the day and my knees will start aching very badly when this happens. The numbness is starting to be more expanded and painful. Tonight has to be the worst though. I woke up and couldnt catch my breath. I looked next to me and realized that my right arm was in a lot of pain. I tried to lift it and couldnt. When I finally did my arm was completely limp from the elbow down, it felt so numb, like my face at the dentist and it was heavy. Took 20 or more seconds to get it back to normal. My forearm is still burning, and as I type my arms are starting to freak again. I dont know if this has anything to do with it, but when I was younger I had a passing out problem. They said it was intracranial pressure but the results were borderline and questionable. Oh, and as this is going on, I tend to be slowing down in metabolism. Ive gained 30+ pounds and I dont know why.
