Suggest Treatment For Bilateral Mastoiditis

My name is Jao. 35. 5 7 height. 64 kgs. I have a chronic dizziness that have been for 6 months. I was diagnozed with bilateral mastoiditis based on city scan (buy my case is not as complicated as what we read on the net). I dont have redness and nothing is swollen behind my ears. no discharge too. My last two EENT said that infection is over. But a General Practitioner told me that I have a blood clot in my right ear that possibly cause my persistent dizziness. I do have a ringing in my ear rarely. Also, when I try swallowing, I can feel like a tolerable pinch nerve somewhere in the right side of my neck. The symptoms are very mild that sometimes I dont get to notice them. The General Practitioner prescribed me a DUXIL. Is there such thing as blood clot in the ear??
