This is something I can help you with. I have osteoarthritis in all my joints except my knees due to the fact they are now titanium and polyethylene. I have yet to find a pain med that the side effects aren't a bigger problem so I have some hacks that help a lot.
Get your vitamin D levels checked! Low vitamin D levels can make your joint pain worse and it is an simple thing to correct.
The best supplements that I have found that help is lots of turmeric and vitamin D. We are talking 5000 mg per day. Magnesium supplements may also be helpful.
I love a hot bath right before bed. It often helps long enough for me to fall asleep. 1/2 cup of Epsom salts in the bath helps too.
Large gel ice packs are wonderful when you are having those swollen sore days. I recommend getting at least 2 ice packs in the 11" x 14" size or larger. Amazon has them for less than $20 and they last forever. https://smile.amazon.com/Chattanooga-ColPac-Therapy-Vinyl-Standard-Size/dp/B000EAPNCQ/ref=sr_1_3_a_it?ie=UTF8&qid=1492731768&sr=8-3&keywords=ice%2Bpack&th=1
Figuring out what foods trigger an inflammation response will go a long way to reducing the chronic pain. Ideally you cut out a whole bunch of stuff for 6 weeks or so and slowly add foods back in to see what your personal triggers are. A good food journal and knowing all the ingredients in what you are eating is key for this to work.
Cutting carbs helps somewhat but figuring out what class of sugars gives you an inflammation response will give you much better relief. I tried eating Whole 30 Paleo and didn't feel any better. I then tried a low FODMAP diet due to digestive issues and discovered that lactose, polysaccharides, and oligo-di-monosaccharides give me serious inflammation problems and joint pain. Many of these sugars are in foods that are really hard to avoid like garlic and onions but it is worth finding out what foods bother you in terms of inflammation and controlling pain.
The best research I am have been able to find on different class of sugars in foods comes from research on diets for IBS patients. Monash University has been testing foods for the types of sugars in the carbohydrates and ranking foods based on the amounts of various sugars so can figure what bothers you. The app is $9.00 but worth it if you are serious about reducing inflammation through diet changes. http://www.med.monash.edu/cecs/gastro/fodmap/
I am also adding more organ meats and fish to my diet to help with nerve pain but I am just starting that so I can't say it is helping yet. I am sourcing the organ meats from local pasture raised chickens and 100% grass fed beef from local farms.
Getting doctors involved....
They love to try and give you shots for things and I have never found any of them to be useful. I have found physical therapy to be very useful if you tend to have aggravate the arthritis by not having the painful joint stay in proper alignment. PT can also help strengthen that muscles around the sore joints and help keep them more stable and reduce grinding in the joint. This is helpful but expensive.
