Simple exercise while lying in bed or sitting in front of the TV -- try leg raises, bicep curls and walking in place. I've had rheumatoid arthritis for 11 years and lost 100 pounds with great results. Just walking around the block gave me great pain relief and removed all signs of depression. It took months just to get to the corner but it helped after concentration and prayer during the walk. Buy a walkman or mp3 player. Also plaquenil worked for years (possible side effect is blindness). Asulfizine and methotrexate didn't work for me. And the last time I checked, Enbrel was actually hazardous to your health. See Worst Pills. org. Good Luck and God Bless;-)
I am sorry to hear you are suffering. I have RA, too, and I know what you mean about longing to enjoy things and be pain free. We all hope for remission and in the mean time have to find a way to come to terms with our pain and limitations.
There are a lot of different drugs out there to help with pain and inflammation and it sounds to me like you need to ask your doctor about exploring them. Have you ever taken DMARDs such as plaquenil or rheumatrex, NSAIDs like relafen or mobic, other biologics like remicade or orencia?
With everything that is going on it is normal to be depressed and with that comes lethargy. If you feel you are falling into a depression you can't shake, you might want to try something like Cymbalta which is suppose to help pain and depression. I have heard mixed reviews on Lyrica, but it is another option in the same vein as Cymbalta.
