There are many areas of human physiology and health where professionals are at the expert beginner phase, but feel the need to appear authoritative (because that's what the patients expect) and so they pretend to know things that actually NOBODY KNOWS, or at least not yet. This is I think the biggest reason why medicine is failing us, and I think some a lot of it is fragile egos but the rest is due to how malpractice law is (not) working.
If there's every anything interesting wrong with you, like soft tissue damage, GI issues or neurochemistry, you're going to learn a whole lot about internal medicine, and you're going to find out the doctor is often making it up as they go.
If you get a good doctor, they are going to suggest things that nobody else even mentioned. If you get a passable doctor, essentially you will be in charge of determining your treatment and dosages (at 3 points in my life the physician was effectively letting me write my own prescriptions, because they couldn't see inside my head or experience my physical symptoms. They're going to set boundaries but you have some responsibility for your own fate. The bad ones are just going to talk to you about how your side effects are expected, or how you'll have a limp for the rest of your life, and you should just suck it up and deal.
(And by the way, if you have anything physically wrong with you, from 'fallen arches' to ligament damage, I can't recommend enough that you get a referral to a sports medicine clinic ASAP. General practitioners and osteopaths know fuck all about how the human body works mechanically, and they're going to tell you to cope with things that are completely fixable, sometimes without surgery. Meanwhile a sports medicine or rehab specialist will teach you how to avoid reinjury, which is something a 'doctor' will -never- do and is actually the most important part of your recovery - staying well).
