Im still feeling really sick and i keep throwing up i cant keep food down but the ER doctors said all they could do was give me pain meds. i cant keep food down at all and im lightheaded and running a fever should i go into my doctor asap or is this normal? i also got my MRI results back and i have cyst's in my sinuses also. Could this cause me daily headaches [because i have them every day that's why i got the MRI] but i cant find any information on the ones in my sinuses is that serious?
