I do believe ear infections can be yeast related.
This was one of my worst symptoms, extremely painful!
I used to get them before I was familiar with candida. I was eating a lot of refined sugars and fruit. Since I’ve discovered candida and changed my diet the ear infections have not returned.
Mine were so bad I would have to call out of work. Ear infections are on the list of candida symptoms and keep in mind that anti-biotics are by far the worst thing you can do if you do indeed have a candida infestation.
