Question explored with the scientific record
Can calcific tendinitis be cured with dmso injections?
No study in this retrieval tested DMSO injections for calcific tendinitis. The question is open, and the burden sits with whoever is selling the injection.
The closest evidence is about DMSO itself, not about your shoulder. A systematic review of 109 human studies found reactions were mostly gut and skin, mostly transient, and dose-related, but the authors admitted they could not pin an exact dose because routes and doses varied so much [2][4]. Nausea ran about 12 in 100 overall and vomiting about 7 in 100 [4]. Skin burning or stinging hit about 16 in 100 with topical use [4]. Cardiac reactions, including low blood pressure in about 4 in 100, appeared only with intravenous DMSO [4]. That matters because you asked about injections, the route with the cardiovascular signal.
| DMSO route or finding | What the record shows |
|---|---|
| Nausea, all routes | 257 of 2214 patients (12%) [4] |
| Vomiting, all routes | 115 of 1611 patients (7%) [4] |
| Skin burning/stinging, topical | 335 of 2141 patients (16%) [4] |
| Low blood pressure, IV only | 115 of 2752 patients (4%) [4] |
| Halitosis, all routes | 607 of 5782 patients (11%) [4] |
Animal data raise a flag the human reviews do not settle. In mice, DMSO alone at a high dose caused notable toxicity, and one of four DMSO-only mice survived to 48 hours [1]. That is a single small toxicology study at an extreme dose, not a human safety finding, but it is the kind of signal a seller will not mention.
For calcific tendinitis specifically, the records here cover needling, lavage, steroid injection, and shockwave, not DMSO [5][6][7]. So there is no efficacy evidence for DMSO injections in this condition at all. The mechanism is plausible on paper, since DMSO has anti-inflammatory activity in animal models [3], but plausible mechanism is not proof of cure.
My call: do not pay for DMSO injections for calcific tendinitis on this evidence. There is no trial showing they work, and the injected route carries a cardiovascular signal. Confidence: moderate that the evidence is absent; low that DMSO injections cure anything here.

The Toxicity of Dimethyl Sulfoxide Combined with the Alkylating Agent MNU on Mice: Focusing on Mortality and Activity Impairment
An acute in vivo toxicology study in mice showing that DMSO is toxic on its own and significantly enhances mortality and activity impairment when combined with the alkylating agent MNU, with all MNU-exposed groups dying within 36–48 hours.

Adverse reactions of dimethyl sulfoxide in humans: a systematic review
In a systematic review of 109 studies, DMSO was associated with mostly transient, mild adverse reactions, most commonly gastrointestinal and skin reactions, with reaction occurrence appearing dose-related.

Dimethyl sulfoxide in topical pharmaceutical drug development: A fresh perspective
A narrative review proposes that high-purity (>99.99%) DMSO is an effective, underused topical penetration enhancer with anti-inflammatory and analgesic activity, and that higher purity may reduce the halitosis historically associated with topical DMSO.
