Mother has kidney infection & is taking cipro (ciprofloxacin) but continues to experience headache in the lower back of the head. is that normal? side effect? what2do

See answer: Headache could be related to having a severe kidney infection especially if was present before starting the antibiotic; or a side effect of the Cipro (ciprofloxacin) antibiotic; or less likely either unrelated or indirectly related such as a migraine. If not relieved by otc meds, or worsening, or associated with other neurological symptoms, then should call the treating physician for advice.
