Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Three days of bactrim is quite early to eliminate the infection.

2. Bactrim is to be taken for at least 5 to 7 days for mild infection and up to 10 days in moderate to severe infection.

3. Please drink adequate water and visit washrooms regularly to flush out the bacteria.

Hope your query is answered.
