A cramp-like pain in the right side of the brain may be caused by migraine, neurological headache or vasospasm headache. Regardless of the cause, if the headache first appears, it is recommended that the patient undergoes a head CT and a Doppler ultrasound of the cerebral arteries in order to clarify the condition of the brain, and then give symptomatic treatment, because it is necessary to exclude headaches caused by brain tumors and brain spaces, which are serious problems. If the Doppler examination reveals a significant increase in blood flow velocity in the anterior, middle or posterior cerebral arteries, which suggests the possibility of vasospasm and stenosis, oral flunarizine hydrochloride and ciprofloxacin can be taken to relieve vasospasm and headache symptoms. If there is no increase in cerebral blood flow velocity, it is considered to be caused by migraine, neurological headache, can be symptomatic oral aminophenoetidine tablets, ibuprofen extended-release capsules and other drugs to relieve headache.
