I feel like I have something caught in my throat?

I can breathe, so it's not anything like I think I'm choking but I can feel it at certain points in the day. Most often I can feel it when I turn my head to the left or when I lay down to go to sleep. However I have also noticed an increase in my allergies in the last few days which is around the same time that the feeling of something being caught happened. I tried a 24 hour allergy med yesterday but it didn't really seem to take anything away with my throat. Any suggestions? Again, I'm not like choking or anything it just feels like a lump in my throat midway down.
