Hey everyone, I started WLS back in 8/2017 with a Sleeve then RNY conversion in 3/2018 and finally a resection with a vagotomoy this February. I'm starting to worry that i am developing a hernia. I started as mild abdominal pain on my right side and my first though was my appendix but was ruled out by CAT scan and ultrasound. The pain is starting to move around my navel and is not severe and comes and goes. Now I am having problem keeping food and liquid down. I just wondering if thiis could be a hernia or would it have been seen on the imaging tests. Are their another signs that could point to a hernia? Thanks for all the help guys! Josh
