Ear ringing and head aches 24/7 since ear irrigation last week. family doctor looked in my ear and said it looked fine. is this normal?

Not normal: If examination of the ear drum revealed no perforation of the drum, that would be somewhat reassuring that no major complication occurred from the irrigation. However if the irrigation was directed directly at the drum instead of at an angle, perhaps enough trauma was caused and resulted in the symptoms. If they persist, I urge a consultation from an Otolaryngologist for evaluation and advice.
