Feeling a weird spot in my throat

I've noticed a few times a day the past few weeks that if I move my tongue or neck a certain way that I feel a spot in my throat. If I press on my throat I can feel the spot touching something but can't actually feel anything from the outside. It doesn't hurt but it also doesn't feel great either. It can't be seen from just looking in my mouth. I've added a picture of where I feel it at. What could it be? I feel like if I go to the doctor for something they can't see or feel they'll think I'm just being a hypochondriac because I just went for breat pain that resulted in nothing being wrong.
