I'm sorry you are suffering from migraines. They can be so disruptive and life-altering. Migraine can affect your taste, but it usually resolves with the attack ending. Many experience a metallic taste in their mouths. Our family had Covid back in July and one of the things we noticed was a loss of taste and smell for quite a long period. It was very odd. Things just didn't smell right and we could only really taste very sweet and salty. It took weeks before our taste started to return to normal and my husband still has not regained his normal taste sensations. It's all very frustrating. I encourage you to hang in there as things will improve with time I'm sure and if they don't you can always touch base with your doctor and see what they have to say. Warmly, Cheryl migraine.com team
