Hi,
I assume that the location you are referring to is groin region. A swelling or lump in the groin region could be a
lymph node, vascular abnormality or
hernia. As you said it is gurgling the possibility of a lymph node swelling can be ruled out. It could be either hernia or a vascular abnormality. A vascular abnormality in the groin area is quite rare. I shall tell you few tests which you can do yourself
Cough Test- Observe whether the lump is increasing in size or an impulse can be felt while you cough. If it increases in size it is hernia
Other test is reducibilty- Try to push back the lump if it dissapears it is hernia
Apart from that i would recommend you to have an
Ultrasound scan of the lump done. It would definitely confirm the diagnosis, most probably a hernia.
If the lump is found be hernia. You need to get treated preferably by getting operated ( Based on the size of the lump and type of hernia)
Wish you the best of health
Bye
Take care
