**The Details:**  

The human body is capable of impressive acts of self-repair, but such processes take a lot of time, and can take a toll on the body. Infection or other complications can also develop, and sometimes a wound/inflammation may not heal entirely or correctly without external help. We see such things done in fiction, but it always seems to just *work*, without any adverse effects or real costs.

**The Question:**  

Let's assume that "external help," whatever it is, is capable of increasing the healing rate of the body to incredible levels. (See: [Wolverine](http://en.wikipedia.org/wiki/Wolverine_%28character%29)) Acting under the assumption that this "external help" merely speeds the process of the body's own *natural* healing ability without necessarily adding any great amounts of energy or any material, what biological effects would a human being experience during the process, and immediately after it was complete? Would they suffer from a lack of proteins due to cells being rapidly multiplied, or a lack of other material used in the body? Would they feel tired due to their system's exertion of compressing weeks/months of healing into a fraction of that time?

As a baseline, let's take a simple abrasion that wouldn't cause any great deal of alarm if it were to happen to you right now. Worst case, it becomes mildly infected. Your body will fight off the infection and, with time, heal the wound. You are now fine, and can continue on with your life. Until...

Suddenly, you suffer another near-identical abrasion that suffers from a similar infection (let's say immediately, because you are an excellent lab experiment terribly unlucky.) I now invoke my otherworldly healing powers and, within seconds to minutes, you're all fixed up. What happens to you in that time?

**My thoughts:**

* The healing process takes energy, generates heat, etc. You will feel quite tired, perhaps warm in the afflicted area, and really want a snack. How this would affect your blood cells (platelets, leukocytes, others) I do not know.
* Scarring will still occur as it is a natural part of the healing process, but it may be reduced, a near perfect example of healing.
* If a bone is broken, it can be repaired, but will need to be set just as a normal bone would have to be. If a finger was cut off, it wouldn't regrow unless that was a naturally occurring process.
* Dependent on HOW the healing helps, it could simply cause the damaged cells to repair and multiply, completely ignoring the normal healing process, but still meeting the end goals, and prevent any possibility of scarring. This is, of course, not the question but would make for an interesting comparison.
* Someone will make a joke about their superhuman healing ability, because I targeted "you" in the question.
* Dammit Jim, I'm an electronics guy, not a doctor!
