With one widely used dressing, sticking is the point. In a wet-to-dry dressing, a wet (or moist) gauze dressing is put on your wound and allowed to dry. Wound drainage and dead tissue can then be removed when you take off the old dressing.
The same process is one of the ways wound care centers remove dead tissue. A wet dressing is applied to the wound and allowed to dry. As it dries, it absorbs some of the dead tissue. The dressing may be left dry or made wet again and then gently pulled off along with the dead tissue. Put more plainly: when the dressing is removed, some of the tissue comes off with it.
So if your dressing is wet-to-dry, it is doing the thing that makes it hurt. That does not mean every painful dressing change is fine, but it does mean the pain can be a feature of the dressing rather than a sign that the wound has gotten worse.
There are two instructions on what to do when a dressing sticks, and they are not the same. For a wet-to-dry dressing: if it is sticking to your skin, wet it with warm water to loosen it. For an open surgical wound: if the dressing sticks to the wound, wet it and try again, unless your provider instructed you to pull it off dry. That exception matters, because wetting a dressing you were told to remove dry would defeat its purpose. If you do not know which applies to you, ask before the next change rather than guessing.
Two other things are worth holding on to. The amount of packing is expected to fall as you improve: as the wound heals, you should not need as much gauze or packing gauze. And pain management is one of the kinds of help a wound care team provides. If dressing changes are the worst part of your week, that is something to say out loud at the next visit.
