I have personally treated my own ear infection and after 2 weeks they started to produce a lot of secretion and itching. My doctor told me to stop the treatment and to build up my antioxidant levels. The skin inside the ear is very sensitive and can get something like an Ozone rash which causes the secretion of a water like substance and a itchy feeling.
I booked 4 Vitamin C and Glutathione IV treatments and after that had the Ear treatment again without any problems.
Ozone rash on the skin is treated in the same way.
