Jane I stopped taking glucosamine and regretted it. So back on it. I pace myself re exercise. For example I cannot walk for too long on hard surfaces like pavements, but can do considerably longer on grass, on woodland paths etc, where I prefer to walk the dogs anyway. I do 30 minutes of strength and yoga/Pilates exercises most morning to keep the old synovial fluid moving too.
I take 1 paracetamol at night and, like you, use voltarol if required. I’ve also found Salonpas patches handy if you don’t mind smelling of wintergreen. And I’ve used a TENS machine when I had a flare up.
Diet-wise I investigated the Nightshade family online. Mixed messages. Some rubbishing the theory while others raved about being ‘cured’ by cutting them out. Then I read a reasoned article which said that there is some anecdotal evidence though nothing proven scientifically but suggested trying an elimination diet for a couple of months to see if it helped. A sensible suggestion, especially when I knew my last flare up was after I’d ingested a good couple of servings of home-made, and very delicious, tomato and red pepper soup.
I’ve cut out all nightshades since and, touch wooden head, had not had a flare up in months until I ate a lasagne my SiL had prepared (didn’t have the heart to refuse when he’d gone to so much trouble) and it tested my theory as I could barely walk next day.
Anyway that’s my theory. I don’t trouble my GP as I feel I know more about my condition than he does, but I did insist on an X-ray recently and it confirmed my self diagnosis.
PS I’m not on any prescribed medication and, again like you, want to hold off as long as possible.
