Is forcing urine out bad?
If you have to force out urine means that there is some obstruction in outflow
enlarged bladder may be due to cystocele, ovarian tumour, PID, Uterine tumour etc in women
Drink lot of water, if still unable to pass please consult doctor immediately
As it is engorged with blood,it compresses urethra and hence makes difficult to urinate.
Yes when there is obstruction, there will be retrograde flow towards kidney
