What could be wrong ? Please help!

It currently 12:52AM and I woke up from my sleep not feeling well.. I'm very very Shakey and a little itchy. My throat is really dry. I don't think I'm having trouble breathing or anything. IV been drinking water and my throat just jeeeos going dry. I feel like if I was having trouble breathing I wouldn't be able to swallow. But I feel like I'm so worked up and having a panic attack that I think I can't breath. I'm not sure why I woke up from my sleep just shaking and shaking ? I got a tooth pulled monday and they have me medication for it I feel like if I was having a reaction to the medicine it would of happened a while ago. Could it be that IV barely ate? Since Monday all IV ate is ice cream and a little bit of spaghetti o's and a couple bites of soup this morning.. but I tried to wake my fiance up and I said " I don't feel good I'm very Shakey and my chest hurts" he feel back to sleep so I tried to wake him up again and said " I'm very very Shakey, itchy and my chest hurts" and all I got was a " yes I heard you I don't think anything is wrong with you is what I'm trying to say" so I really don't know what to do. IV been awake for about half hour now just shaking. I'm not sure if I'm having a panic attack or what ? I just wanted my fiance to wake up just in case I had to go to the hospital or just to hold me. my main concern is why did I just wake out of my sleep all Shakey and really dry throat?
