What type of doctor should I visit next? I have heart palpitations (i can hear my heart beat loud, I visited a cardiologist he had some tests done on me like echo-cardiograph and ecg which showed normal results), upper back pain (i visited an orthopedist and he did my x-ray and mri and found mild left uncovertebral arthrosis is seen at c3-4 level causing minimal foramina compromise and he prescribed me myospaz forte tablet for 1 week, it didn't solve anything) and irritable bowel syndrome (i visited a gastroenterologist, he had all types of test done on me like ultrasound scan of abdomen & pelvis, stool analysis and blood test and found nothing abnormal and he concluded that I was afraid of going to the college and that I am lying to my parents). I think all these problems are caused by my upper back. I have also visited a neurologist. But these doctors doesn't understand the problems. They just see the reports (which doesn't show any abnormality) and write me some tablets which doesn't work. I am unable to go to school because of my stomach problems, when I am far away from a toilet I feel anxious because I feel like I need to use the bathroom all the time. I have decided to quit school and study from home but I am not able to concentrate. What type of doctor should I visit to solve these types of problems?
