Wasnt feeling well yesterday. clammy, heart pounding, felt like i was going to pass out and ended up throwing up. today i have been feeling off balance, and my head feels foggy and off balance still. legs feel heavy and soar. what could be going on?

Despite the severity of your symptoms, I consider them nondiagnostic at this time. Possibilities include an inner ear disorder or early viral infection. Development of fever& diarrhea,aches? would favor a viral gastroenteritis. Presence of vertigo aggravated by head and/or body motions favor an inner ear disorder. For now, rest,drink adequate fluids,take dramamine as needed for dizziness. ?SeeMD
