Medicines & claims
Is it ok to take a painkiller every day?
No. Taking painkillers daily or most days can cause a new problem: medication-overuse headache, where the body gets used to the pain relief and the pain returns when it wears off. If you need something more than about twice a week, that is a reason to see someone rather than to keep taking more.
What this does and does not tell you
This is general information, not a diagnosis. Only a clinician can examine you, take your history and run tests. The same symptom has different causes in different people.
If something is sudden, severe, or getting worse quickly, get medical advice rather than reading on.
