Severe damage symptoms and conditions

My mother was given avelox for a bronchial infection appoximately one week ago. Within 3 days she developed large pustules on her arms, legs, neck and a few on her trunk. She suffered from dizziness, memory loss, confusion and paranoia. She had panick attacks due to the itching which was severe. A trip to redi care brought no help, the staff said they had never seen anything like it and provided a topical steroid cream. Her family physician who prescribed the drug did not seem concerned at all. She is depressed and has had dizzy spells causing her to fall. My mother is 76 and although not as sharp as she used to be she is very concerned about any long term damage this drug may have caused. I am attempting to get her in to another clinic for treatment as her primary DO acts as though the whole thing is no big deal. The area worst effected is behind her knees and on the inside of her arms. I have read the side effects regarding tendonitis and tendon damage and am very concerned.
