There's not enough information to give you appropriate advise with regards to the reason why your mother is feeling the way she is at the moment.

No matter how difficult it is , urinary tract infection can easily be treated . It is just the matter of doing urine cultures , finding out if there is bacteria that is grown and finding out the sensitivities and then giving appropriate antibiotics. Some women are prone to recurrent infections and in such cases, small dose of antibiotics can be given on daily basis to keep the infection under control.
