Hello there... I understand your concern about your health condition and I appreciate that...there are many reasons for throbbing headache it may be due to increased blood pressures, migraine, cluster headache, refractive errors, meningitis,sinusitis, reffered pain from somewhere else... So detailed history and examination with relevant investigations is necessary... Kindly consult nearest neuro physician they will do the needful.

Please get your eyes checked. Seems like a problem in your vision. Also get your Vitamin D and B12 levels checked. Lipid Profile test will also be healthful. Take proper rest and use screens on ur Tv set and screen guard on mobile. It will help
