Is any of this happening?
Be seen today
Seek prompt medical advice for a new pattern of pain, unexplained weight loss, persistent fever, a swollen or hot joint, pain that repeatedly wakes you, or new weakness or numbness.
These signs may have causes other than chronic pain and need urgent assessment.
And for anyone, someone who:
has abdominal pain that is severe, constant, or getting worse

Does any of this apply?
Book an appointment
Arrange a routine appointment if pain has lasted more than three months, keeps returning, disrupts sleep, limits normal activity, or is becoming harder to manage.
You should also seek review if a treatment is causing side effects or no longer appears helpful.
And for anyone, someone who:
has a symptom that has lasted more than a couple of weeks without improving
Every sign above is quoted from the sofidex article on Chronic pain. If you are not sure, err upward — it is always reasonable to be checked.
