Brief Answer:
Supportive care and diet lifestyle changes.

Detailed Answer:
Thank you for asking

I read your question and i understand your concern. Rheumatoid arthritis is very debilitating condition and pain can be unbearable and strictly reduces range of mobility. Due to severe inflammation, bone erosion and even deformities can occur. I am afraid rheumatoid arthritis has no cure. So you will need to continue with the supportive cate and strong enough pain killers and DMARDs ( Disease modifying anti rheumatic drugs).

Physical therapy exercises to aim at reducing range of mobility are helpful. KNow your limits. Dont put your body through alot. Apply heat and cold compresses over the swollen and painful areas for the relief of pain,

Now the coughing up mucus clearing on medications and recurring should be evaluated for both local throat causes, lungs causes and gastric causes. With use of Pain killers and NSAIDs, acid reflux and gastritis are very common and that can cause coughing as well as mucus in it. Some say its a feeling like something is stuck in throat. If so then its the side effect of rheumatoid arthritis medications and needs diet and lifestyle modification for the relief. Also the lungs functions should be evaluated and worked up to rule out some respiratory infection cause for it.

I hope it helps. Take good care of yourself and dont forget to close the discussion please.

Khan
