A one-sided headache lasting for 6 months should not be ignored, as it may be due to conditions like migraine, cluster headache, or other underlying causes, and proper diagnosis is important before treatment. Instead of relying only on temporary pain relief with medicines like paracetamol or ibuprofen, a doctor may prescribe specific treatments such as Sumatriptan for migraine-type pain or preventive medicines like Propranolol or Verapamil to reduce the frequency of headaches. Along with medicines, lifestyle changes such as maintaining regular sleep, reducing stress, staying hydrated, avoiding triggers like caffeine excess or alcohol, and limiting screen time can help significantly. It is important to consult a doctor or neurologist for evaluation, and tests may be advised if needed, especially if the headache is severe, worsening, or associated with symptoms like vomiting, vision changes, or weakness, as early and proper treatment can provide long-term relief.
