Who can you believe?

I am and have always been hesitate to seek medical attention since I turned 18. It was easy when I was younger you go to the doctor and all  you have to do is stick your tongue out, they would weigh you, take your blood pressure, and stick that cold stethoscope on your chest and tell you see you next year. But I am aware that as an adult I have to go for my annual physical  and I do.

I always feel like I am walking into a box full of gyrating and jumping germs when I go the doctor - I mean isn't that why people go to the doctor?

Somethings you can try and treat yourself and it works; then sometimes you just end going to the doctor anyway because your self treatment did not work.  So when you go there you expect results because they have been trained and educated on how and what to do for you.   Well we have to remember they are human and that like with anything you will always find someone who doesn't quite understand the importance of why things are done or just don't care.  I don't know what to make of this situation but when you get test results from your doctors or tests- don't you accept the results?  Are we not suppose to trust technicians, doctors, and nurses?

Please tell me what I can do?
