The ominous words of my rheumatologist are "There is no cure for inflammation". But...
There are medications for arthritis talk to your doctor for this.
I find any and all of the supportive techniques and equipment is helpful:
This includes rest on a comfortable mattress, hot &/or cold packs (I have five), splints
( properly fitted, of course), hot or cold showers/baths, stretch exercises and mild exercise. Distraction ...T.V., movies, documentaries, music helps 'move ' you above the pain. Chatting with a friend. A gentle hobby - keeps your spirits up too. As well as a support group to learn from each other and remind you that you are not alone!
If all else fails, there are pain meds. I use Emtec-30.... these are like the old '222's', but do not have caffeine...but try everything else first.
This is a long road. Only you will know what helps. All the best to you, my fellow sojourner!
