thanks for your query at HCM
something moving down sensation in throat might be due to defect in oesophageal motility or reflux disease.
1 drink plenty of water
2 avoid coffee and tea
3 avoid spicy foods, and late night foods
4 take tab pantoprazole
2o mg twice daily before meals
these changes will decrease your symptoms.
even after this symptoms does not subside further investigation like endoscopy
might be needed.
hope this will help you
