I am a 27 year old female. I have upper body aches and dizzy spells. My neck, shoulders, upper back and upper chest. when i breathe in or out it hurts in my chest and upper back and it feels as if my throat is blocking something in my chest. could it be as a result of a bad night's sleep? - ive been using 10 day melt away (to lose weight) for 6 days now. yesterday i was serverely dehydrated. but ive basically been drowning myself with water. since yesterday, could that have anything to do with me feeling so bad today? Never really had dizzy spells before until today.
