I Have Been Getting Allergy Shots For 8 Months Snd

I have been getting allergy shots for 8 months snd it has been great. However,ok had some laryngitis for a couple of weeks apnd he referred me to an ENT. This Dr, thought I had silent acid reflux and told me to take Nexium for 2 weeks. He also proceeded to schedule me for a 24 ph test, CT scans, barium swallow. After taking the Nexium over the weekend, my voice was 90% better. I think because my father had throat cancer, he is pushing all of the extra tests. After reading up on them, I feel like if I clean up my diet (which I have for the last week - no more Dr. pepper, etc, that I should not rush into the tests. I feel great now. What is your opinion.
