Well come to HCM
I really appreciate your concern, if this is suspected case of Urinary tract infection
then better to get done the culture sensitivity test for right choice of drug and cure, because in female UTI does not comes around easily, giving steroid
in suspected case of infection is not advisable this could flair up the infection and may create complication, differential diagnosis need to be take in consideration, and for this all the routine tests need to be done, autoimmune disease
may not be cause, hope this information helps, take care.
