I read your question and I understand your concern.
First of all considering your right side symptoms, if it hasn't been done already, I would consider head and neck MRI imaging to investigate for brain and
cervical spine issues at the origin of the headaches.
Medicine like Acemiz treat only the pain they don't do much to prevent it, so it is only natural it will return. If it is indeed
migraine headache (usually unilateral, pulsating, nausea, vomiting, increased sensitivity to light and sounds, lasting 4-72 hours) then regular preventive treatment is available, several options like
propranolol, amitriptiline,
valproic acid,
topiramate, flunnarizine are recommended, they are all prescription drugs, so you should contact your doctor.
If the pain has different characteristics, more info is needed to determine its type and treat accordingly.
I hope to have been of help.
