^Although I don't necessarily agree with your diet advice, the advice of beef as a universal recommendation, I do totally agree that diet as a modulator of inflammation is important. This is well recognized in the medical world.
It's just tricky to develop into an evidence based treatment recommendation because it varies so much by person, which makes it difficult to study and difficult to implement. That, and doctors are not the professionals to oversee that kind of lifestyle stuff.
I will also TOTALLY agree with you that an aversion to woo should not equal a dependence on doctors alone. Doctors tend to be HORRIBLE at treating pain. They can be experts at treating issues that cause pain, but if, and only if the problem can be readily identified and is actually treatable.
I've had severe pain my entire life and I've seen dozens and dozens of doctors, and only the ones trained in pain management knew anything about managing pain properly.
The only doctors who have ever successfully resolved pain for me were the surgeons who took out my infected appendix, and the doctor who gave me a puffer when I had an asthma attack.
Otherwise I've been given a giant pile of prescriptions, which sometimes help in a pinch, but come with side effects, especially if taken long term.
Then there's all of the other shit. What works, what's woo? Who should you trust? Who's full of shit???
Well the key to navigating the world of non-doctor treatment is to give up on the need for explanations, and to generally ignore any explanations given.
Acupuncture works for some people for some reason. We have no idea why, we have theories, but no actual facts. Many chiros and naturopaths and whatever will give detailed explanations as to why they work...they don't know, but in the end, it doesn't matter.
If it works for you, then great. Don't question it, just do it.
It's the same with taping, cupping, and even massage therapy. The RMTs are taught detailed rationals for why what they do works and how it should be done. Meanwhile, it's all just a theory, but it works! Consistently! For almost everyone! Yay!
Truthfully medicine isn't any different. Doctors don't know why most of their drugs work. The difference is that they aren't usually taught bullshit reasons to explain it. They're doctors, they don't need PR to justify what they do.
These allied health folks, fitness folks, whoever, aren't at fault. This is what they're taught. They're taught theory as fact and they repeat it as if it's fact. That's where woo is a problem.
It's hard to sell people on alternative treatments if the sales pitch is "fucked if I know how it works, but you might as well spend a couple hundred bucks and see if it helps". So the industry doesn't promote that narrative. Plus what people in pain usually want even more than relief is answers.
I've "helped" countless pain patients just by being able to explain to them why they're in constant pain. Honestly this alone accounts for 99% of my patients satisfaction. Actually reducing their pain is usually just a bonus in terms of how much they value my service and its cost, even though it fails to help a lot of people. These industries know that, it's why they focus on giving clients answers.
Do bee stings help with chronic conditions? I don't know, maybe. But if they do, I guarantee no one else knows why either, especially not the chiropractor with pages and pages of explanation as to how it interacts with the body.
There's no question that a certain diet, a certain exercise, and a certain combo of treatments will probably help anyone who experiences pain. It's just very very hard to figure out which combo, because there's no reliable scientific way to determine which body will uniquely respond to what. And each type of provider only has evaluation techniques that allow them to say if their treatment MIGHT help, and the answer is almost always 100% "yes it might".
So that's really the best way to approach any ongoing bodily issue. Get the doctors to check if there is an objectively solvable problem, or if there's a problem that could get worse without intervention.
Beyond that, sure, read about options and the various theories as to why certain approaches might work, but take any and all explanations with a grain of salt. That doesn't mean these treatments or diets aren't powerfully effective for some people, just learn to have a healthy respect for how mysterious the human body is.
Respect that no one has answers, but a lot of people have options to offer, and the vast majority of options that can help you with chronic pain will not come from an MD.
It's trial and error. And if it works great, but don't kid yourself that you have much of an idea why something works. Just keep doing it as long as it works. And just because your woo-y alt medicine provider is probably entirely full of shit as to why they're recommending certain treatments, doesn't mean that full-of-shit woo huckster can't help you. Statistically, they can probably help you with pain more than the MD who is less full of shit but also has no good options for you.
