Repairing water-damaged paint (possibly drywall)?
If it was indeed just recent &amp; not an ongoing for years situation. Then, let it dry for a week or 2 &amp; see how solid it is then. As long as it feels as solid as before &amp; the rest of the walls, then definitely scrape off what bubbled, split &amp; wrinkled paint you can so there are no lifting or flapping edges.

You'll want to fill those new low spots with Joint Compound or Spackle for a nothing ever happened end result. Lay that on in very-very thin coats just as thick as the paint you have surrounding the scraped areas. Dry-Sand with sandpaper to perfection &amp; a lot of dust or Wet-Sand with a wet sponge for no dust. Let dry &amp; do another Compound or Spackle coat, if needed &amp; sand again.

Then, roller-on a Stain Blocking Primer &amp; let that cure for 2-days, you shouldn't need a 2nd coat but do that if it's needed. And finally, roller-on your paint, 2-coats over the primer-ed areas &amp; even do the rest of both walls to get everything uniform &amp; to use up your paint...of course do this with the Primer too, prior to the paint, in order to use that up as well.
