Yeah, tendonitis sux.
Been fighting it for almost 40 years - in my shoulders, arms, fingers, toes... ridiculous.
For some peeps, colloidal minerals help. I've seen classic cases of tennis elbow disappear almost overnight after CM supplementation. Just be aware that some companies cheat by using sulphur to extract the minerals (usually from "old", buried organic plant matter), instead of relying only on soaking in water. You can tell who the culprits are by taking a whiff from the bottle's opening immediately after breaking the seal. If you smell sulphur, it ain't kosher.
I mention this 'cause inorganic sulphur's a common cause of long-term backache. Peeps don't realise it, but the shit builds slowly in your system, accumulating from food sources that otherwise shouldn't contain any. Just as in the case I mentioned above, it serves as a means of speeding up processes, such as the drying one. This is why dry dog "cubes" are a classic source of them. When I detox (heal sick ones) dogs, green puss oozes from their eyes within a week or two. This is the sulphur finding its way out. In the case of humans, you can take MSM, which IIRC is extracted from pine bark; it's an organic form of sulphur, which is good for you, and as is usually the case when you replace an inorganic (from rocks or made in a lab) form of something with an organic (plant-based) one, the bad form is "forced" out. In this case, back-pain relief in cases where folks have given up after decades.
