This is a tricky question - new studies actually show that people who skip breakfast aren't at all heavier than people who don't skip it. The myth that people who regularly breakfast aren't as heavy as people who do skip it has arisen through bad scientific studies that were being conducted in the past. Newer ones, however, show that this isn't the case. For that reason, your question is invalid :)
When taking a lumbar epidural steroid injection, its common to feel pressure/discomfort but shouldn't experience severe pain. So the answer would be uncomfortable at most not painful
