I can say from personal experience only...."not scientific" that if i forget to taky my prilosec....i will and do have a mean headache w/ the gerd that follows. it's like clock work and i directly attribute the headache to my untreated gerd! I'm curious to see if others have this same experience.
Im a true believer that Acid Reflux is related to anxiety. Depending on how hard ya tke it. If its really messing with ya, then you can gain anxiety, which will give you ear aches, or a water like sensation in your ear. Also, Acid Reflux controls your diet. So, if you used to drink alot of coffee or soda and had to quit because of Acid Reflux, that can give ou headaches. Also, stress and anxiety can give you headaches. Always remember, Acid Reflux really SUCKS!, so it comes with anxiety, therefore we always have to include anxietys synthoms when trying to leraqn more about our new sickness, 'Acid Reflux'. That is very inportant to remember!
My husband said his doc mentioned the relationship between gerd and headaches. Recently my priloset just stopped working and I am experiencing severe headaches. So, I think there is definitely a relationship. I'm on my way back to the doc for a new drug.
Note that I have been taking meds for gerd for 10 years and after a few years the medicine stops working and I have to change to another.
