picking at underwing feathers

my 11 yr old blue fronted amazon has recently started picking her right wing underside. when a youngster she fell from her playpen down into the legs of a bar stool and injured that wing. I didnt know at the time this was the case as she quickly recovered, within an hour. but it became evident as time passed, years, that she couldnt fly. the lower joint failed to develop. this was not a problem all these years until the last 6-8 wks when this fussing and wing flipping started. today she has become quite involved in constant apparent discomfort.
