Continuous pain above one eye for six months requires a detailed re-evaluation by a doctor or a neurologist. Since paracetamol and Zevert MD (betahistine) only offer temporary relief, you may benefit from preventative rather than temporary rescue medications. Depending on the exact diagnosis, effective long-term options might include daily preventative medications like amitriptyline, topiramate, or specific anti-inflammatories like indomethacin. Your doctor may also recommend an eye examination or an imaging scan to rule out any local issues. Please consult your healthcare provider to discuss these targeted treatments safely, as they can provide much more lasting relief.
