I have a syndrome called minires witch is fliud build-up in the ear from allergic reactions that can cause ringing temporay loss of hearing and equilibreium problems like vertigo. Its not a syndrome that can easily be fixed if you have anymore symtoms like that you sould mention it to your doctor. They can percribe medication s to help blood flow in the ears buts ome meds can make asthma worse. I can't take anything for mine for that reason so i try to just live with it. Seach engine it if you want to know more hope it helped. : )
No, you should not assume that your ear problems are not due to allergies. They may be, but tinnitus is not a symptom of allergies. You should request consultation with an ENT specialist; one with a major interest in ear problems, especially the causes of tinnitus. In the meantime, consideration of shots would be unwarranted.
Good luck.
I do believe differant Meds can start Tinnitus,and even continue after you stop the meds but the meds triggered it,since I was prescribed Meds a couple of years ago (never had it before) I have had a low whooshing Tinnitus ,worse whenh I wake up,it has never gone away, I hope yours does.
