<s>[INST] I went to the emergency room on wed. night due to a heavy feeling in my chest, rapid heart rate,  shortness of breath, dizziness, nausea and vomiting,and I have had neck pain and back pain for a few weeks now..  the only thing they did in the ER was an EKG and and took my blood pressure in the lying down, sitting and standing positions.Then they just said... your heart is beating a little fast but its not irregular so we're going to be discharging you and we believe this is due to a virus.  I left there at 5:00 am thurs. am.. here it is Friday and the heaviness in my chest is just finally starting to get a little better.. still have a terrible headache, but now new symptoms.. my hands and feet are swollen and there is some numbness in them and my urine is dark orange.  Should I go to the doctor ... a different one.. to see what is going on?? I have had the headache the entire time.. for three days... which I believe caused my nausea, I am 44 year old female. I am 5'1" and about 97 pounds. [/INST] Hey there,According to me you must consult a different doctor very soon.As it seems some major problem related to your blood or kidneys. </s>
