Hello, Female age 40. I woke up on Sunday morning with an awful metallic taste my mouth. It was there when I swallowed food/drink. It has persisted to get worse over the last few days. It is extremely difficult to eat due to the taste that occurs when I swallow and now even smell. I went to urgent care yesterday and the physician did not have an answer other than to put me on antibiotics thinking maybe it could be an infection. I have been congested in my nose for and may have sinus infection but it has not been confirmed. Have you experienced patients that have come to you with this issue in the past? Please advise. I started taking amoxicillin yesterday. Today the metallic taste is at its worst since.
