Infection is a risk of any surgery. However, if you have a recurrent hernia, and if that appears to be the source of yoru symptoms, then repair of this hernia shold be considered (perhaps by using a lapaurscopic approach this time).
As I am not involved in your medical care, I cannot offer you any specific medical advice.
