Hi,
How are you? Do you still experience the symptoms you mentioned? Aside from meuromuscular issues, conditions affecting the ear may be responsible. If it persists, it is best that you have this checked by your doctor for proper evaluation. Direct clinical examination, complete neurological examination and diagnostic tests will help determine the diagnosis. A referral to an ophthalmologist may also help rule out eye issues. Take care and do keep us posted.
Are you pregnant?
I'm only asking this because I common early pregnancy symptom is dysgeusia is the medical term for a change in your sense of taste; most often, you'll get a sour or metallic taste during pregnancy.
You might not be pregnant because migraine sufferers can experience illusions or hallucinations of taste as gustatory aura symptoms. The differential diagnosis of these symptoms includes temporal lobe epilepsy, now more commonly called complex partial seizure disorder, so that a neurological examination is warranted in each case presenting with such gustatory symptoms.
