I have some osteoarthritis, it runs in my family. I manage on occasional use of codeine/paracetamol, single dose per day, used before activity when I know there will be pain, but I wait for an hour so my brain adapts to it before trying the activity that causes pain. Paracetamol is not good for the liver, so if you ever need it to be regular, go with DrThumpenstein's advice and get some checkup that lets you know if you're safe to use it more than a minimal and occasional use. AFTER anything that has caused pain and inflammation I will sometimes use ibuprofen, because I have learned that like allergies, breaking the cycle with a brief intervention can help avoid the need for prolonged dosing. I ran that notion by a doctor after having figured it out by my own observations (and a similar situation with fluticasone furoate for hay-fever like symptoms). He agreed, and said that similar self-perpetuating feedbacks exist in the body, and many conditions arise purely because easy regulation has failed to work. I back off on all such meds when possible, they tend to work better when I need them next if I do that.
Regarding asking for medical advice online, I have had doctors tell me it's fine, if we're careful. They're all for INFORMED consent, and they like it when we make the effort, and it certainly beats being inundated with the 'worried well'!
Last but not least, if in doubt, and a doctor isn't helping, get a second opinion! You may NEED a diagnosis, likely also an X-ray. At that point you're free to accept advice or treatment as you decide, or to refuse it outright, but whatever you do, you need as much certainty in diagnosis as you can get before that kind of decision, even if it's just to narrow the range of advice given by most medical sites out there.
And if an actual doctor is posting HERE, all to the better, we're damn lucky to get anything like a house call these days.
Afterthought: if you buy oranges in bulk for saving money, maybe avoid that, I discovered that too many oranges WILL provoke some excruciating pain in existing arthritic joints. No-one told me about this, but I learned after three boxes over two years, that the timing of events was undeniable. If I moderate the oranges, there is never that kind of pain. I was told that food sources of purines were a thing to watch, but I love marmite and never got pain after it, but oranges were a different matter. I don't go with hugely complex dietary advice, we're born to be omnivores, but it's worth avoiding any proven specific once you discover one. Oranges may be fine for you, but something else may not be.
