Does any of this apply?
Book an appointment
Arrange a routine appointment if swelling keeps returning, has no clear explanation, or is interfering with daily life.
You should also seek review if established idiopathic edema becomes more frequent, no longer improves overnight, or is accompanied by changes in urine output.
Every sign above is quoted from the sofidex article on Idiopathic edema. If you are not sure, err upward — it is always reasonable to be checked.
