The pain you are feeling in your cuts can be caused by a couple of things, Sweat, or dirt still in the cut and the best way to flush is under normal high speed water and to promote quicker healing they say to do the same thing, hold under fast running water, it washes out the infections and dirt. If by opening back up you mean separates without bleeding then it could benifit greatly by this process, but if it starts bleeding it needs treatment because it is open blood the most dangerous thing ever to attract germs and bacteria. Just watch it and if the skin starts changing colour around it seek that ER or if the pain starts traveling out of the immediate area like up your arm do the doc thing but you will be OK and I'm with you on the Monster Vs Aliens 3D thing.
The sun will rise again and tomorrow will be another day I know this because we get there ahead of the rest in Australia East coast
