after reading your hiistory i can tell you may be you are having some changes in your facial nerve
so to confirm that you need to consult neurologist
.The facial nerves control a number of functions, such as blinking and closing the eyes, smiling, frowning, lacrimation, salivation, flaring nostrils and raising eyebrows. They also innervate the stapedial (stapes) muscles of the middle ear and carry taste sensations from the anterior two-thirds of the tongue. As you are having problems related above i guesses it as facial nerve swelling in early stage so take care and by using corticostreoids in this case everything will become normal nothing to worry.Thank you.
