Any irritated condition is characterised by inflammation. The most common medicines prescribed for RSI are anti-inflammatories. So it stands to reason that RSI is tissue-damage, caused by repetitive strain, and anywhere tissue damage is occurring immune mediated inflammation takes place.
Tenosynovitis is inflammation of the fluid-filled sheath that surrounds a tendon.[1]
So, the treatment we were taught was to address the physical injury by removing, retraining, or engineering the problem away, then give nutritional supplements that support tissue repair and help down-modulate the inflammatory response: Omega 3 EPA / DHA (fish oils), Quercetin, Rutin, Vitamin C, Bromelain, B12 & Folate, Magnesium (as citrate or diglycinate, or both), plus Turmeric and Ginger. And also give supplements that target musculoskeletal / connective tissues: Silica, proline, lysine, cysteine, glutamine, Manganese, B5, B6, Iron (as iron amino acid chelate), copper, zinc (as amino acid chelate). Where the condition has progressed to considerable over-all wear and tear of a join the also throw in Glucosamine and Chondroitin.
The theory goes: remove the mechanical cause of the condition (repetitive strain causing tissue damage) and the condition will resolve itself. Put in the nutrients the body needs to repair the damage and the condition will improve faster. Sometimes the damage is so far progressed it will respond much better if the nutrients are taken too.
Once the condition is under control we then direct the patient to look in to seeking advice to strengthen the affected joint.
I don't know about the state of nutritional medicine outside of Australia, but here we have some really good formulations available off the shelf and others as practitioner only formulas - so you need a consult.
I'll pre-empt the "supplements don't work" argument and say: yes, taking iron oxide or magnesium oxide doesn't do anything. There are formulations that are poorly absorb and poorly utilised by the body. Have a look in to, for example, magnesium diglycinate and magnesium citrate vs. magnesium oxide. Look in to mixed ascorbates with citrus bioflavanoids (Quercetin and Rutin) vs. pure Ascorbic Acid. High does Turmeric and Ginger work so well as anti-inflammatories and blood thinners they are contra-indicated if a person is taking blood thinners / blood pressure medication, eg Warfarin.
Anyway, getting carried away. Thought you might be interested.
