Where do you get information about your health or illness?

Do you get most of your questions answered by your doctor, another healthcare professional such as nurse, pharmacist, physio, etc? Or do you rely on family and friends? Or the internet? Would you rely on what you learned elsewhere, or have to visit your doctor anyway? Do you rely on what your doctor tells you or do you check up on it? How do you know if what you are hearing is trustworthy and good quality information?
