I'd recommend getting a second opinion as well...even just for peace of mind. Once you know that it is/isn't from the mesh, then you can plan accordingly. I'm not very familiar with hernias and mesh, etc...I just wonder if it could be your glands.
I hope you feel better.

Get a second opinion. My cousin had his mesh fail and had to have the hernia op redone. It took me quite a few years to not feel any pain or discomfort at the site of the hernia. I am an active mt biker and also cross train with weights. For quite a few years I could not do sit ups without discomfort. It's been 6 years.
