You can also get your Blood pressure checked to rule out hypertension.
Can be sinusitis too . Antihistamine , decongestants and steam inhalation might help.
oh, get your eyes tested too!
hi azky,this could be due to quite number of causes(sinusitis,migraine,raised intracranial pressure to name a few).Try some pain killers along with decongestants and ofcourse steam inhalation, if not relieved,do consult the doctor and get yourself investigated(blood pressure,CT scan etc).Take care!
