Does any of this apply?
Book an appointment
Arrange an appointment if the restriction lasts, keeps returning, becomes worse, or affects sleep, work, walking, or personal care.
You should also book an assessment if you have ongoing swelling, morning stiffness, unexplained weakness, or several affected joints.
Every sign above is quoted from the sofidex article on Limited range of motion. If you are not sure, err upward — it is always reasonable to be checked.
