The past two days, when I try to swallow food it feels weird, and eating food is feeling like I'm trying to swallow a pill or something, it's just difficult. I almost feel like I will choke if I swallow food. It also seems like worse because now I have been extra cautious when eating and this probably adds to it. However, today I've dranken just a bunch of Ensure & made a smoothie. I tried to eat some rice, but had trouble with that, even just a simple olive. I've had this trouble in the past, but it only lasted a day or so. I also had vocal nodules a while ago, but they healed.
Is this common? Even with thicker liquids like smoothies and ensure I am having trouble drinking, and it's rather annoying and making me anxious.

I'm a 19 year old male, in excellent shape, and no other major health problems.
