I've been experiencing some numbing within my entire leg for about a year now, before, it would be 2x/3months, then I had a break up from a 7 yr relationship, had nausea and vomiting, panic attacks, and stomach issue. Ive been experiencing headaches too and having trouble sleeping so I used an e-cig to make me sleep. At 1stl it worked, but then I got used to it, alcohol doesn't make me feel sleepy at all. I'm awake for 24 hrs and longer on some days, maybe 3-5x a week. I'm a pre-med student also. Then, I keep having this excruciating pain, and uneasiness within my legs. I also noticed having weak grips too. Though, trembling hands were seen since I was 14 y/o. I tried elevating my legs while sleeping, since it attacks whenever I lay down (sometimes even when sitting) it works sometime but most of the time it doesn't. It's numbing me, am I having a problem here? :((
