why my ear is itching

Persistent ear itching can be quite bothersome, and while it’s sometimes challenging to pinpoint the exact cause, there are a few common explanations worth considering. Since your doctor didn’t see any infection or wax buildup, it’s possible the itch may stem from other factors. Dry ears can result in itchiness, especially if you’ve been cleaning them a lot as it may strip the ear canal of natural oils. Consider avoiding excessive cleaning or inserting anything in the ear canal, as this can exacerbate dryness or irritation. Alternatively, contact dermatitis from products like shampoos, hairsprays, or even earplugs could be the culprit. To rule out or confirm any topical allergies, discontinue the use of new hair products for a bit and see if there’s any improvement. In some cases, the problem can arise from a fungal infection, which is not always easy to see but typically comes with itchiness and sometimes a musty odor. If the itch continues, especially with that occasional ringing, it may also be worthwhile to consider seeing an ear, nose, and throat specialist, as they can further evaluate for less obvious issues like Eustachian tube dysfunction or early signs of tinnitus, which sometimes manifests with itching. As for diet, while food allergies can manifest in many ways, consistently itchy ears solely related to diet are relatively uncommon. Nonetheless, keeping a food diary to monitor any connections between foods consumed and changes in symptoms could be informative. Given your frustration and the persistence of your symptoms, further professional evaluation would be a prudent step, particularly if any new or troubling symptoms arise.
