Thank you for your question.
I am Dr Saha, I shall try my best to help you.
In UTI symptoms can be varied.
There can be minimal symptoms in mild infection.
If the urine culture confirms infection, then it is better to take the antibiotic.
The effectiveness of cranberry in UTI is still not established.
You can read this link on it.
Please try to take plenty of fluid.
If you feel weird & spacey, then you need to take an urgent review by doctor.
An examination in urgent care or ER can be considered.
Other issues can be there too like dehydration, electrolyte changes, systemic infection.
A consultation with urologist will be helpful.
I hope this information helps.
If there’s anything else I can do, please let me know.
