Should i go to the doctor, emergency room or should i wait and see if it gets better i dont know what to do and it hurts to breathe sometimes to.

That is a lot of: varied symptoms in a 22 year old female. Unless you have a severe issue such as worst headache of your life, severe abdominal pain - the Emergency Room may not be your best bet. This may need to be worked up over time. I suggest that you begin with your primary care provider who can determine the best course of action after assessing these complaints. Take care.
