Hi Jonathan45177
First to remember is that your ear is still swollen my ear was swollen for at least 3 weeks after my surgery and that was a surgery not an impact type of head injury such as yours. Your ear really does need time to stop swelling and settle down. You are only on day 3 of the meds so give them a chance.
Once your ear has had a good chance to heal your dr may have a different outlook for you.
PLease just let your ear heal up more and try not to worry once things have settled down your dr will be better able to confirm a long term diagnosis.
Did you see an ENT dr? If not you probably should
Keep posting and I will keep checking back, stay healthy and take it easy for a while.
Best wishes
