Do OTC joint supplements work to reduce pain from inflamation?

I over stressed both hip joints going up and down a ladder about 25 times, to replace my dead ice-maker. The next day I had severe pain in both hips joints. I've now had a cortisone shot in each hip joint with little relief. The only thing that really helped is a wheel chair, which was really inconvenient as I live alone and have a small house, large yard and two dogs to care for. I almost always refuse to get physical therapy as I don't believe that making my joints hurt worse is going to help. I am considering using an otc joint supplement but can't afford to spend a bunch of $ on something that may or may not help. Any suggestions as to what may (or may not!) help would be greatly appreciated. My effort to save a hundred dollar service charge to have someone install the ice-maker for me has resulted in hundreds of dollars of medical bills. Thank you for any advice you can gife me!
