Hello I am Dr Ravinder Sharma ENT surgeon
On the basis of information provided it appears that you are concerned with the trauma in the throat because of catheter. This is a treatable condition.You will require ENT examination and possibly an endoscopy
of oesophagus to look for the extent of damage. Depending on the extent of damage treatment can be planned. I will not comment on the problem of reflux right now. It is better to take care of the injury
in oesophagus and once it heals it will need a review for reflux. At the same time an antacid
may be of help for you. This will neutralize the acid content of gastric secretions and thus your symptoms of reflux will decrease for the time being.
I hope this answers your concerns. Feel free to contact me if your need more information on this
With warm regards
