Thank you for the input.
I am very sorry for your symptoms.
I understand your concern.
Antibiotic can take some time to act.
It can take 2-3 days too to have its full effect.
When you are taking it for 3 days, I feel you need a review by doctor.
The antibiotic may not be working or there can be a complication.
Repeat tests like urine culture would be needed.
An ultrasound, blood work can be taken.
I hope this information will be helpful.
If you have any query, please feel free to ask.
Your satisfaction is my goal.
