Yes, you should be worried because you don't know what it might be, however be sure you don't breathe while you are drinking the water that might cause the feeling you're getting, but I'm unsure since I am not a doctor and I can't tell, so go to a checkup to an actual doctor.
Leave "thanks" if I have helped you anyway or made a stupid joke you've liked
