I just had laparoscopic hernia repair two days ago where they used mess, i have a huge egg like bump on my left site and a low grade fever , help?

S/p lap: Please call you doctor today and let him know. It could be seroma, hematoma or infection

See your surgeon: What kind of hernia repair- groin or abdominal? Either way, the most likely causes of the bump are a normal fluid collection (seroma) that will go away on its own, or it could be a recurrence of your hernia. Especially if you have a low grade fever, you need to call your surgeon and probably need to be seen to rule out a problem.
