Hi, I understand your concern. General weakness, lac of resistance & probably uncontrolled diabetes is basic cause of getting repeated infections through out body . You need to get your mother investigated to find basic status of her health. Get her through physical examination done by a physician to find probable diagnosis & get it investigated along with- - Complete blood count, Mx. test, - Urine -microscopic & routine , _ fasting & post meal blood sugar test/ glucose tolerance test, - culture & sensitivity teat ( from the exudate/ tissue currently infected) to find the bacteria & the effective drug, Consult an expert physician who will advise her specific treatment according to the reports. These need to be accompanied by general majors like - good hygiene/ cleanliness - light nourishing diet with high proteins, vityamins, minerals, iron- as per doctor s advise. - Rest, mild exercises once she is settled, - POsitive thinking of the patient induced by love, assurance, nursing . I am sure you mother will recover with methodical management as described above. Thanks.
