The appropriate setting may be the clinician’s office, an urgent care service, or an emergency department depending on severity and availability.
Call emergency services for severe trouble breathing, chest pressure or pain, coughing up blood, fainting, sudden one-sided weakness, difficulty speaking, a seizure, new severe confusion, or signs of a serious allergic reaction.
These symptoms can have many causes, but they require immediate assessment.
Contact the care team for routine or prompt advice if symptoms gradually change, a rash persists, joint swelling increases, Raynaud episodes become more frequent, or medicine side effects develop.
Report possible infections, especially when taking immune-suppressing medicine.
Do not wait for a scheduled visit if symptoms are worsening.
Seek urgent same-day medical advice for a painful finger or toe that remains pale, blue, or dark; a marked decrease in urination; new significant muscle weakness; persistent fever while taking immune-suppressing medicine; or rapidly increasing swelling.
New chest pain, breathing difficulty, heavy bleeding, severe headache, or other major symptoms during pregnancy need prompt medical evaluation.
Routine follow-up may include a review of symptoms, examination, blood pressure measurement, and blood or urine testing.
The schedule depends on the diagnosis, current treatment, and organs that may be affected.
Some people also need periodic lung, heart, eye, or bone monitoring.
