My son is 24 years old, a non smoker and a social drinker. He is approximately 5 10 and 150 pounds. He has been seen by an ENT and had a needle biopsy approximate 1 year ago for a quarter size lump at the very top of his neck. Test came back normal. Within the last month, he returned to the ENT and was scoped and the doctor reported no blockage. He has had a series of blood drawls and everything has come back within normal range. He is now experiencing difficulty swallowing and claims he feels that his airway is block or limited. He stated that he feels oxygen deprived. He is also complaining that he has an onset of acid reflux. Last year, he was treated with Claravis for severe acne. He is currently not on any prescription drugs and takes daily vitamins. Since there is clearly something wrong, I am questioning what type of doctor should I be making an appointment with other than a general medical doctor. Thank you.
