The Back Pain Doctor
Trigger finger, or stenosing tenosynovitis, occurs when a finger or thumb catches or locks as you move it, because a flexor tendon can no longer glide freely through its pulley at the base of the digit. It is more common in people with diabetes or rheumatoid arthritis and in those who do repetitive gripping.
Assessment is usually clinical — the diagnosis can generally be made from the history and examination, and imaging is not routinely required. Where the diagnosis is uncertain, ultrasound can help.
Most cases respond to non-surgical care, including splinting, activity modification and an image-guided corticosteroid injection, which is often effective. If the finger is locked or injection does not help, referral for a trigger finger release is appropriate. Because trigger finger is linked with diabetes, its presence can be a useful prompt to review blood sugar control.
The options below include the treatments offered at The Back Pain Doctor. Listing a treatment does not mean it is recommended for this condition. The evidence, likely benefit and role of each option are considered against the diagnosis, examination findings, imaging where appropriate, patient goals, risks, cost and alternatives.
This is the starting point for most musculoskeletal conditions.
The priority is to identify the likely pain generator, explain the condition clearly, modify aggravating load and build a realistic plan to restore strength, movement and confidence.
Evidence is condition-specific; it is not a universal pain treatment.
Shockwave is best framed as an adjunct where the diagnosis fits. It is generally more established for selected tendon and plantar heel pain presentations than for many joint or nerve conditions.
Read moreEvidence varies substantially by condition, tissue and preparation method.
PRP may be discussed in selected tendon or joint presentations. It should not be presented as a guaranteed regenerative treatment, and uncertainty, cost and alternatives should be discussed.
Read moreMay provide symptom relief when the pain generator is a joint, bursa, tendon sheath or other defined irritable structure.
Injection treatment may be discussed when pain is limiting sleep, function or rehabilitation. The expected benefit is usually symptom control, not tissue regeneration.
Read moreClinical evidence is still developing and guideline support is limited.
EMTT may be discussed as an adjunct in selected presentations, but should be presented with clear uncertainty and never as a replacement for diagnosis, load management or rehabilitation.
Read moreEvidence is condition-specific and generally less established than exercise-based care.
Prolotherapy may be considered in carefully selected chronic ligament, tendon or joint-related pain presentations, but it is not a first-line treatment.
Read moreMost relevant when focal myofascial pain is a clear contributor.
Trigger point treatment may reduce pain from focal muscle spasm or myofascial tenderness. It should be paired with movement restoration, strength work and recurrence prevention.
Read moreRelevant only when the history and examination support nerve irritation or entrapment.
Nerve-focused treatment may be discussed when there is a plausible peripheral nerve pain generator. Progressive weakness, major neurological deficit or red flags require a different pathway.
Read moreThis is general information only. Suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of uncertainty, expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
