I am a 26 year old female with no history of any medical problems at all (except my back goes out once in a while and I go to the chiropractor to fix it).   About 2 weeks ago, I woke up in the middle of the night and could not feel my legs.  They were numb, cold, and tingling.  I can move them fine and walk fine and have no balance issues.  I went to  the chiropractor thinking it was a pinched nerve.  He adjusted my back but told me I probably have MS.  It really scared me so I went to the ER right away.  They refused to do an MRI (needed more evidence) and sent me home after drawing blood.   I went to my primary physician and he said the bloodwork was fine and he had no idea what I had.  He put me on Prednisone and Nifedeprine, neither of which helped at all.  I just returned to him today and he took me off of both and said it was pointless and maybe I should learn to live with this.   I made an appointment with a neurologist but that isn't for 2 more weeks and I'm very scared.  Everyone just tells me I probably have MS and need to live with it.  The women at work say it's probably a brain tumor and I'll die.  I think they're gloating about it.  But moving on...   I have numbness in my legs, tingling in my feet, and a cold left foot.  I get joint pain too, very mild right now, even in my hands.  My heart has been beating irregularly a bit and my blood pressure at the doctor's about 4 hours ago was 90/60, which he said was not a big deal but I feel a bit lightheaded.   What should I do?  Any ideas?  The doc did say my Vitamin D level was 15, which is supposed to be low, but he wasn't concerned and said it couldn't cause my symptoms.
