Does a breast implant revision hurt as bad as the first time?

I understand.  Who wants to hurt? 
The answer to your question takes another question.  What type of revision are you contemplating?
Just changing from one implant size to another does not hurt nearly as much as the original surgery.  Major revision that would involve the muscle may hurt as much as the original.  We need to know what you are having done and what you already had done to answer the question.
Hopefully your surgery will be the "not nearly as bad" type of revision.

Since the pocket has been formed, there is generally less discomfort post breast implant revision. However, consult in person with an experienced and expert board certified plastic surgeon who can address that question specific to you.

In my hands and my experience I have never had revision hurt as much as the primary surgery. The answer is simple: you already have the incision, you already have the space, you already have the muscle stretched out. Add to this a FIELD BLOCK of novocaine around the edges during surgery and you can expect a much more comfortable surgery. It is more technical, buy much less painful and a quicker recovery regardless of the extent.
