Welcome to Just Answer.
When did you have the urine test?
Did you have urine culture?
Did doctor prescribe any medicine for it?
I would advise to have an urine culture.
Urine infection can cause bad odor.
It can cause urgency as you can not hold it.
Culture involves collecting urine in a sterile container.
Then a specimen is grown in culture medium in the lab.
This helps to detect the type of bacteria.
This also helps to detect the antibiotic or medicine suitable to treat it.
Please write where do the swelling develop during period.
Did you get the swelling checked by doctor?
Swelling during period can occur from congestion. There can be an inflammation or infection. Endometriosis needs to be checked for.
An infection or inflammation can cause painful sex.
Please take an urine culture as I suggested. You can discuss it with your doctor.
Contaminated water or filth coming in contact with the opening of urethra can predispose to infection.
Bacteria then ascend the urethra towards bladder.
If you have any further query, please feel free to ask.
In case of urinary tract infection or to prevent it we advise to take shower & not to use bath tub.
A ominous tumor or growth or cyst can be picked up by scan.
When your scan did not show any such thing, you should not worry.
But infection may not be picked up by scan. You will need urine tests, blood counts etc.
Do you have any further query? Please let me know.
Those would subside. It is not a tumor.
You can take blood tests as a precaution.
