a bulging eardrum can cause vertigo due to the pressure. this usually means a middle ear infection but cephalexin would not be my drug of choice to treat this in an adult although i don't know your dosage or medication history. the medicine probably is not your culprit but rather your ear disorder. vertigo is also common in inner ear infections and these are often viral. viral infections do not respond to any antibiotic therapy. since i have no way of knowing your diagnosis or severity of symptoms you will need to consult your medical provider if you are not getting better.
3 days on cephalexin for bulging ear drums. swollen glands of the neck sore throad. this morning experincing vertigo. i am concerned about the vertigo. do you think it could be caused by ears or med?
