Hi ! Your operation was done 8 months ago for bilateral inguinal hernia
. Now you are feeling the same old sensation on the left side only. Have you noticed any type of swelling on your inguinal area just as you had before the surgery. If it so, then it could be a recurrence of the hernia on the left side. But due to improvement in the surgical techniques laparoscopically, this is a remote possibility even though possible.
The other possibility is entrapment of nerve
of the mesh with any other abdominal viscera, or fibrosis
at the site of surgery.
If there is no swelling, and not any major problem, you can wait for some more time, and see if the problem subsides of its own. Otherwise you will have to get yourself reviewed by the operating surgeon. Wishing you an early recovery.
