I am having urination problem for a month. Urine comes out normally at the first flow but at the last moment of urinating urine comes slowly and sometimes in drops. At the last moment of urinating if I sit a while and create pressure then small amount of urine comes out. Thus taking time to empty the bladder completely. I have done usg, urine test, blood test, creatinine, hba1c, everything is fine but the problem is occurring not all the time but sometimes. Is it a minor problem or not?
