Tendon issues happen because of some sort of unexpected spike in stimulus or acute injury like perhaps in your case? The Barbell Medicine forum is pretty useful as you get actual PTs and powerlifting MDs giving free advice. I think the medical thinking these days is you’ll need to train your way out of it. Tendons, even sore ones, crave load. It’s counter-intuitive but resting them can just cause the injury to hang around. Still there are conditions around how much pain is permissible etc. so it might be nuanced.
I’ve had a wrist complaint for years but lately it seems like a lot of heavy carries, wrist curls, forearm and grip work has made it vanish.
If we’re talking about supplements, it’s not generally considered an inflammatory condition these days either apparently, so anti-inflammatories aren’t recommended.
