Hi,
Welcome to the ehealthforum. I am really pleased to help you out. You need a physical examination by a gynaecologist to rule out any local injury/tear in the vagina/cervix at the time of the delivery which might be causing all the symptoms which you are going through.
An ultrasound of the pelvis should also help in delineating the cause of the pain & discomfort youâre going through. A urine analysis/urine culture will help in knowing the status of the urinary infection. In case, it is there, a course of antibiotics will facilitate the treatment of the UTI.
It is very difficult to diagnose online without physical examination and will thus suggest you to consult a gynaecologist. I sincerely hope this information helps. Take care.
