I am a 19 year old girl who has been feeling sick for about a week. Since last night I have had a racing pulse of over 125 bpm and I'm very lightheaded and a little dizzy. I haven't been able to drink much at all for a couple days because of nausea and vomiting. My urine is very dark and almost brownish orange. I couldn't sleep last night because of my racing pulse. Do I need to see a doctor now, or is it something that can wait? Should I be concerned?
