Arthritis = inflammation of joint irrespective of cause so response to meds will vary from folk depending on individual 'cause'
Also consider muscular spasms, cramps and simple bruising, repetitive strain, tendonitis and ligament inflammations.
It's a realistic sadness that as we age we don't recover so well but because of the multitude of variations o specific cause it's clear that one person's home remedy may not suit another.. Buzzwords/phrases such as 'anti-oxidants to scavenge free radicals'.'anti-inflammatory nutrients' and then various charms – copper bracelets, magnets or photodynamic therapies – the latter gaining credibility.
Green-lipped muscle, shark cartilage and bovine cartilage supplements were fashionable as substances rich in some nutrients and chondroitin and glucosamine.
Evening primrose oil (also blackcurrant oil, borage oil) as sources of GLA and precursors which metabolise to inflammatory and anti-inflammatory products and then add Omega-3 fatty acids (Cod liver oil example) to push the metabolism to anti-inflammatory products preferentially.. To get an effect you need quite large doses – usually more than the levels sold in health food shops jumping on the bandwagon of 'nutraceuticals'
Remember, many folk will praise a product when it was just their placebo response.
Aspirin has much to commend it – but as with all these products check interactions with any meds you're on.
The latest fad that is proving itself in Vitamin D supplementation – again quite high doses needed and most of us are way under on theoretical levels – more so if huddled into a shed and in winter and windows filter light wavelengths. Cod liver oil is such a source but watch you don't overdo the vitamin A in it or go for a purer source.
Selenium and Vit E as antioxidants are also traditional – Brazil nuts as a source of selenium.
There should be enough pointers above for some reading but watch out stick to quality literature sources as opposed to hype and opinion.
Lastly. Whilst very sceptical I did go through a period of messing about with acupuncture and surprised myself by finding some animal patients with very good responses. You can get a placebo response there if the owner claims it's working but if a patient with proven severe osteoarthritic changes (x -ray) starts to trot about after a few sessions it does make one a believer at least as pain relief for a subset of patients.
