PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Report any signs of infection, especially pulmonary signs associated with pneumonia, influenza, and invasive fungal infections. Common pulmonary signs of infection include persistent cough, dyspnea, chest pain, coughing up blood, fatigue, fever, chills, and loss of appetite.
Periodically assess impairments such as joint pain, muscle aches, fatigue, skin rash, and conjunctivitis to help document whether drug therapy is successful in treating CAPS and related syndromes.
Assess any new bone or muscle pain to rule out musculoskeletal pathology; that is, try to determine if pain is drug induced rather than caused by anatomic and biomechanical problems.
Periodically assess body weight and other anthropometric measures (body mass index, body composition). Report a rapid or unexplained weight gain or increased body fat.
Monitor IV injection site for pain, swelling, and irritation. Report prolonged or excessive injection-site reactions to the physician.
Instruct patient to guard against infection (frequent hand washing, etc.), and to avoid crowds and contact with persons with contagious diseases.
Instruct patient to report other troublesome side effects including severe or prolonged headache, vertigo, irritation of the nose and pharynx, or GI problems (nausea, diarrhea, abdominal pain).
