Thanks for writing your query.
are single sided headaches.
After reading your post it seems that you are not having migraine headaches.
You should get yourself clinically examined(preferably by a Neuro Physician and an ENT specialist
I would also suggest that you should also get a CT/MRI of head and neck done to rule out any internal cause for the headache.
You can take painkillers like Ibuprofen
one tablet twice daily after meals along with an antacid like Omeprazole
40 mg once a day.
I hope this is helpful to you.
