You can also go to liquid form if needed in many things.
I've had this issue as well, and at one point, was dipping my pills (especially the tablets) into coconut oil just before I swallowed them with plenty of water.
There could be a number of things happening to create this situation, but if you've had your thyroid tested, it may be a transient thing, or at least just due to having Lyme (muscle weakness in the throat possibly).
