Have your thyroid checked. A lot of times when it is slightly swollen it will cause you to cough ,or "choke" or have. a hard time swallowing. Even fluids can do this. This happened with both my parents long before the thyroid started to "bulge" out of the neck. It was hypothyroidism. I hope this helps and I pray that this is just a fluke and don't cause you any further issues. Good Luck 🙏
