Hi. My mom is deaf in one ear from a long ago injury. For the last 4 years she has been losing the hearing in her "good" ear for 4-6 weeks usually in May/June. Sometimes it slightly improves. She does not seem to suffer from allergies. Doctors always give her antibiotics which do not work. Any ideas either tradiotional or holistic would be appreciated. We think it may be due to pressure or a blockage in her inner ear. This is new for us. Thanks!!
