When i urinate in commode i see bubble formation mainly when i directly urinate in water and it decreases to almost nil extent when done on the walls. I tried urinating on floor for bubble also but there were no bubbles or froth even when i urinated upon standing. There is no problem either but the only thing which is bothering me since 3 or 4 days is that i wake up after around 5 hours of sleep at night but there is not a strong urge to urinate means sometimes i sleep again also but also i am having allergy in nose due to which sinus is swollen and sometimes it create breathing difficulties. I am undergoing treatment with allegra m for it. So i want to know that is there any serious issue? I have no issues with urinary system other than this. I am also having pain in upper back but yes i am undergoing treatment for gerd and infection followed by indigestion so it mainly happens at the time of trapped gas episodes.
