Hi and welcome to HCM.. I thank you for posting your query here and I m definitely going to help you out.. I being a surgeon, we encounter so many such cases day in and day out.. I read your question completely and have understood it well enough.. I will analyze all your points and provide necessary explanation and treatment.. 1. You say it hurt while passing urine.. Yes, I m suspecting urinary tract infection, Uti as the cause which made you experience pain on urination. 2. Big container water and kept passing urine every 10 seconds!! Well, honestly how much ever big container water you drink, passing urine every 10 seconds is abnormal. This simply suggests that you are suffering from urinary tract infection, Uti and frequency is one of the most important symptom associated with Uti. 3. And, yes.. There s no major problem as such. Do not worry. Please note these following things.. A. Get urine routine and B. Urine culture.. This will help us to establish the diagnosis and treatment later.. Culture will tell us the responsible organism for Uti and the sensitive antibiotic to be taken. Later we can plan accordingly.. Hope this helps you, In case you need any further assistance, please let me know. Take care and God bless.
