Severe pain on one side of the head, along with giddiness for 15 days, can happen because of migraine, inner ear problems, sinus issues, nerve irritation, cervical spine problems, blood pressure changes, or stress-related headache. However, continuous symptoms for many days should be assessed properly, especially if the pain is becoming stronger or affecting daily activities. A neurologist is usually the most appropriate specialist for persistent one-sided headache and giddiness, while an ENT specialist may also be helpful if dizziness, ear symptoms, or balance problems are prominent. Tests such as blood pressure monitoring, eye checkup, MRI, CT scan, or inner ear evaluation may sometimes be advised depending on symptoms and examination findings. Adequate hydration, proper sleep, stress reduction, and avoiding excessive screen exposure may temporarily reduce headache triggers. Vomiting, weakness in the arms or legs, blurred vision, difficulty speaking, fainting, or sudden worsening of the headache may indicate a more serious neurological problem and may require prompt medical attention.

Headaches along with feeling unwell can happen due to many common causes such as stress, lack of sleep, dehydration, viral infection, eye strain, sinus problems, anxiety, skipped meals, high blood pressure, or excessive screen time. Sometimes headaches are also linked to tiredness, body weakness, poor eating habits, or long working hours without proper rest. Getting enough sleep, drinking adequate water, eating meals on time, and reducing continuous mobile or computer use may help improve symptoms. Resting in a quiet environment and managing stress may also reduce headache frequency. Mild headaches often improve with proper hydration and routine care, but repeated or worsening symptoms should be checked properly. Seek medical care if the headache becomes severe, causes vomiting, fever, blurred vision, weakness, confusion, or difficulty speaking, as these symptoms may need urgent attention.

A headache lasting for around 10 days should not be ignored, especially if the pain is severe or keeps returning daily. Problems like migraine, stress, lack of sleep, sinus infection, eye strain, dehydration, anxiety, high blood pressure, or long hours on screens can all trigger long-lasting headaches. In some people, even irregular meals or too much caffeine can keep the pain active for many days. Try giving your body proper rest for a few days and reduce phone or laptop use as much as possible. Drinking enough water, sleeping on time, and avoiding loud noise or bright light may also help if the headache is related to stress or migraine. Some people take pain medicines repeatedly, but frequent self-medication can sometimes make headaches more stubborn over time. Medicines/treatment should be taken only if advised or prescribed by your doctor. If the headache is becoming more severe, disturbing sleep, causing vomiting, blurred vision, weakness, fever, or neck stiffness, consult a doctor to rule out any serious underlying problem.
