If you can get some grape seed extract - that is the only thing that ever helped me - I had the exact same symptoms in many major joints from my systemic lupus - really bad pain, inflammation, fluid, swelling. The grape seed extract needs to be taken at 100mg per 100lbs of body weight, if possible. If you take it with other antioxidants, even better. It is a natural anti-inflammatory - so won't totally destroy your kidneys like what the doc gave you is doing to them, and it also repairs and removes free radicals in the system that cause disease, inflammation, damage, breakdown of the body. If you can get grape seed with resveratrol (also from grapes), you are 5x as good. I had my mom get it from Costco for the inflammation in her wrist (she's 64) when I saw her wearing wrist braces. She listened to me and in two days, no more braces, and I have not seen her with them since! I highly recommend it. I began using it when I didn't even know that I had lupus or that it was supposed to help with inflammatory conditions, lupus, joints - also supposed to help really reduce chance of cancers, and prevents/heals damage caused in the body by the high sugars in diabetics, such as vascular breakdown, poor circulation, poor healing, bleeding in the capillaries in the eye that makes them go blind, etc. Most disease and breakdown in the body is contributed to by free radicals and the damage they do - grape seed extract is the superman of antioxidants and scavenges these free radicals and rids your body of them. I used to sell it years ago before it became a product you could get on the shelves (early 90's) and we knew a lot about the wonders it was doing for people. You can find it a lot of places now, but look for quality, too.

Also, if I ever have a knee go out, I always keep it well wrapped, night and day, and that makes a HUGE difference in how fast it recovers and how it feels. Make sure you have some good ace bandages on there until you are fixed up! Try Tommy Copper, too, that might be a good product for that purpose. Just Google it.

Take care!

Oh, p.s. - the other thing I have found that greatly helps the pain in joints and soft tissues anywhere is 100% pure emu oil - just rub it in - like magic it takes away pain, for me anyway. Not the blue gel stuff with emu in it - just the straight-up emu oil - and keep it in a cool place so it stays fresh.
