I am a man of 43 years old recently when i felt severe and constant headaches on to left part of my head,i went on meet a doctor and he checked my bp told me i have hypertension 170/110 and the reason for headaches is it.he gave me amlong-A after i took the pill daily in the nights it was fine,but having a doubt i met another doctor after i finished off the total amlong-A pills for 15 days.when i met second doctor there was a gap of a week without amlon and the second doctor again checked my bp and it was 160/100 and asked me to sit for 1/2 an hour and rechecked then it was 140/90 so he prescribed Aten-50 daily in the morning.But after taking Aten it was not fantastic to my body or stomach and all when compared to amlong,so please advise me what to take and when to take.I am 43 years old w/o diabetes and any other problems except this severe headache that too from 5 years or so but only occassionally almost in every 6 months.when the head ache comes my head goes out of my control gets a feeling to die.I can't see the things clearly when the head cahe strikes.Initially before getting head ache i can't see anything clearly and after 1 hour or so i get headaches which lasts for 2 or 3 days.I fell from my bike once some 5 years ago and got a struck of my head to the raod at a force of 30kgs.But there was no bleeding injury or any dizziness anytime after that injury just little swelling and decreased within 10 days and thereafter evrything was fine.please diagnose.
