Hello,
Sharp pain in the scalp on one side is commonly due to
cluster headache, migraine or
tension headache. If you are hypertensive, control your blood pressure at all cost. Stay well hydrated, take adequate sleep, avoid stress and anxiety. Take home made food and maintain your food intake timing. Since pain is in the right parietal region, it could be indicative of Nummular headache due to arachnoid cysts. Sometimes,
trigeminal neuralgia evolves into nummular headache.
You are suggested to get clinically examined by a GP/
Neurologist to detect the factor causing you discomfort. You will have to get CT, MRI, MRA, ESR, CRP and few blood workouts to get the treatment started. Your treatment will depend on the pathology detected. In the meantime, you can take
acetaminophen, one SOS for relief.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
