Thank you for your inquiry.
In my opinion, there is very little if any relationship between allergy and tinnitus per se. However, allergic individuals with allergic rhinitis can, by obstruction of the Eustachian tube, perhaps aggravate ongoing tinnitus that is produced by another cause. Also, there is very little evidence that allergy therapy, including allergy injections, has any beneficial effect on tinnitus.
However, I have copied for you below an abstract of an article presenting a different view. The authors of this article, otolaryngologists, promulgate a different view. Thus, this is an area of controversy.
Nonetheless, in my opinion, allergy is not a primary cause of tinnitus and there is no strong evidence whatsoever that therapy of allergy, including allergy injections, can ameliorate this condition.
Thank you again for your inquiry and we hope this response is helpful to you.

Ménière’s disease (MD), which by definition is idiopathic, has been ascribed to various causes, including both inhalant and food allergies. Patients with MD report higher rates of allergy history and positive skin or in vitro tests compared to a control group of patients with other otologic diseases and to the general public. Recent immunologic studies have shown higher rates of circulating immune complexes, CD4, and other immunologic components in patients with MD compared to normal controls. Published treatment results have shown benefit from immunotherapy and/or dietary restriction for symptoms of MD in patients with both allergy and MD.
