Those of us that have been training forever tend to look at injecting with suspicion.
We didn’t need that, must be some are not training right.
Really, we didn’t have the knowledge, techniques and medications safe to inject joints then.
Last two decades plus, injecting is more common, in horses but also in humans.
Youngsters in sports, top athletes, weekend warriors and everyday person with some problem gets injected.
I had a hip injected twice, a thumb, a knee and a shoulder also.
Worked for hip, thumb and knee, didn’t for shoulder, had to have surgery anyway.
While some may misuse injecting, I doubt that it is as common to misuse as some think.
We don’t know yet that a joint was injected here.
