An ENT is a good bet. You might be allergic to something you are eating, drinking or inhaling (smelling.) What has changed in the last 2 months, can you think? Did you change your laundry soap or perfume? Shampoo?

That it hit your throat could be anything but possibly something you're eating or drinking. Try eliminating everything and going with pure water first. (Don't forget about toothpaste and gargle stuff... eliminate them too , especially if they are new to you.)

I hope you find a reason soon. ((hugs))
