well we know that it is not bugs crawling in your middle ear space but without a hands-on examination i really would have no way of offering you a patient-specfic reason for your symptoms. there can be many reasons from middle ear infections middle ear fluid eustachian tube dysfunction otitis externa etc. that could cause those symptoms. you will need to see a medical provider so you can be properly examined diagnosed and treated.
it feels like bugs crawling around behind my eardrum. what could this be?
