You will not be able to have them done at the same time. In fact, run away if someone offers this. Most hernia repairs involve the placement of prosthetic mesh and contamination of the mesh is catastrophic.
An open repair can be done under local or general anesthetic and is a day procedure. In most cases, if there is no urgency to repair, it can be done at your convenience, to allow for recovery time.
As someone else stated, you need the opinion of a general surgeon as to whether you have a hernia and how and when it should be fixed. Your internist may be able to recognize one but I am sure that he/she has not fixed many.
Most general surgeons do hernia repairs. Best to ask around to find one that can do a good job for you. If you are up Peterborough way, I can fix yours.
