I am 20% for Hernia if I was to have to have another surgery will it bring my rating up?
If you have surgery for a service connected condition, the rate will usually rise to 100% while you recuperate. Then there will be a C & P exam and your rating will be determined just as before, by symptoms that you experience after the surgery. If the surgery is a success, your rating could fall to 0% service connected or if not, it could rise dramatically. We won't know until after you have the surgery and are recuperated.
