most likely , this is temporary , and will get resolved by its own. Take rest. However if you have vertigo, loss of hearing , then you should see your doctor.
common causes for ringing ears are-
Allergy, high or low blood pressure (blood circulation problems), a tumor, diabetes, thyroid problems,Medications like anti-inflammatories, antibiotics, sedatives, antidepressants, and aspirin.In your case, it seems to be temporary, if the symptoms dont get resolved in 4-5 hours , then see ENT doctor.
My opinion is that you can wait for maximum 5 hours, more and if the symptoms dont disappear , then see ENT doctor.
All the Best.
