Dear eaglemom10: Anytime there is scar tissue that is manipulated there is a possibility that it can tear - and this can conjur up a variety of sensations. However, if this is unchanged or gets worse after a couple weeks, you should let your doctor know.
It can take over a year for scar tissue to stabilize and become inactive. Whereas it's not really likely to "tear" it after that long, exam could make it more sore for awhile. The firmness in the area may never go away; but as was said, it shouldn't get worse. If the soreness continues or gets worse, have it checked again. By the way, vitamin E doesn't do anything for scars topically. Scars get paler as time passes (usually) no matter what you do or don't put on them.
