 [ Symptoms ] how long will it take until antibiotics start helping my ear infection  i was prescribed an antibiotic for an ear infection 3 days ago and i have yet to feel relief from the dizziness and pressure in my head what should i do [ Disease ] assuming you are talking about a middle ear infection you should have experienced relief in three days if a you were properly and accurately diagnosed b your ear infection was due to a bacteria and not a virus and c the antibiotic you are taking was the proper choice and dosage failure to respond to your treatment is a reason to call your medical provider for patient specific advice since you are still having dizziness and head pressure it would be wise to be re examined
