50 years old , pain on right side , high blood pressure

Hi,
Your concern is regarding the headaches that you are having. From the symptoms these headaches look like migraine headaches. The International classification of headache disorders has defined migraine as having unilateral location, pulsating quality, moderate or severe intensity, aggravation by routine physical activity and association with nausea and/or photophobia and phonophobia.

Treatment of migraine involves using a cold compress to the area of pain, resting in a room with little or no sensory stimulation (light, sound, and odors), withdrawing from stressful surroundings and sleeping. You can also try over the counter pain killers like aspirin or acetaminophen. If still the symptoms persist, then please consult a physician for specific anti-migraine therapy (triptans and ergot preparations).

Uncontrolled blood pressure can also be one of the causes of the headache and thus it needs to be controlled.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
