Hello sir and thank you for posting your query here and I'm definitely going to help you out..
Welcome to HCM..
I being a surgeon, we encounter so many such cases day in and day out..
I thank you for posting your query here and I'm definitely going to help you out..
I will analyze all your points and provide necessary explanation..
1. The urge that you had was of
urinary tract infection, Uti because it responded to antibiotic
ciplox.
2. Urge is decreased or subsided..
This means, your Uti is resolved but I suggest you continue antibiotic for total of 7 days at least instead of 5 days..
3. Well established Uti, we treat them for 10 to 14 days or at least one week..
4. Urethral opening, dark and brown is absolutely normal and you need not worry for that..
Yes, take this from me.. Do not worry at all!!
I hope this helps, in case you need any further assistance, please let me know.
Take care..
