My wife had an attack of viral fever recently. The aftermath has left her with debilitating pain in her joints and an allergic reaction on her palms, which are painful and red especially at night. Blood tests have cleared her of any virus except slightly elevated uric acid and CRP level of 9.The doctor has prescribed Arcoxia and Doloneurobion for the pain which really hasn t helped. Yesterday she had a tablet of Xevor which has improved the situation considerably. She is planning to continue with with this. She is also on long term dosage of Nexium 40 mg and Inderal 40 mg per day. What is the dosage and duration that she can continue Xevor? Is it safe with her existing medication? Will the joint pains leave any residual disfigurement?
