Hello,
Thank you for asking at HCM.
I carefully read your question and understand your concern.
By what you explain a painful lump in the left lower abdominal quadrant, next to the
urinary bladder and that bulges with
cough, the most likely diagnosis and the first thing that comes to mind is hernia.
It is very important to urgently go and see a doctor, if hernia is painful it means you are at risk of bowel
necrosis and might need quick
hernia repair surgery.
A visit first will help the doctor understand how likely is it that you are having a Hernia. he will examine you lying and standing, at rest and on coughing and see if the lump bulges or not.
Than the doctor might ask for an abdominal
ultrasound in case he has high suspicion of hernia and this will say for sure if you have hernia or not.
According to the findings the doctor might decide on blood tests that might be needed also.
Hope this is helpful and answers to your question
