I Need To Know What's Wrong With Me... I Had

I need to know what's wrong with me...
I had surgery almost 3 weeks ago (a full hysterectomy). The pain comes and goes with this healing process. But for two days I've felt awful. Starting last night i got really dizzy like I was about to pass out. And faint. I turn white as a ghost my eyes burn. I have a metal like taste in my mouth my body from low belly down to my feet hurt and I can hardly stand. The taste in my mouth is awful. My heads spinning I can't get my color back and my body is on fire. I'm super weak like hard to hold my self up and I'm dizzy and neuasous.
