What if we like pain? :3
Pain is good!
Pain and pleasure are, ultimately, two sides of the same coin. Where pain is a warning for our conscious that there is damage, and pleasure is, of course, the feeling of ecstasy we feel during carnal activity or relaxing motions (E.x. Message).
Since the nerves for pain and pleasure are quite similar, and in some cases the exact same, they can begin to feel pain after a certain threshold has been cleared. However, in this, some people can mentally ignore or completely change the feeling(s) they receive from pain, to be pleasure. Whether or not this is due to childhood trauma or a simple fetish, would be from one individual to another.
On the note of mental anguish, where a few of the replies have stated that it would be a warning that there was something wrong, I'll go a bit farther and, in hopes to answering the initial question, explain what I know.
For mental pain, there are an extremely large variety and consistency with each variation, as well as a more attenuated feeling felt by each specific individual.
For instance, depression can be caused by both a chemical imbalance and a psychological or emotional trauma that the individual either fails to cope with, or refuses to cope with. An example of this would be, if a husband, who has loved his life for years on end, watches his wife die in front of him, suddenly loses the will to live and kills himself, it would have been external stimuli which influenced the decision in himself. However in the case where the depression is a chemical imbalance, the feelings the individual in question feels, may actually be due to malformed tissue, lack of proper nutrition or exercise (Yes both eating habits and physical exertion affect mental stability and serenity), or a simple matter of one organ producing too much melatonin or not enough seratonin(Along with a host of other chemicals). In this case, where the afore mentioned items come into play, a various amount of psychological effects can be seen.
A standard and widely encountered issue would be depression. Depression can range from simply seeing the world as a sullen place, and not feeling well, towards a more cynical and devastatingly provocative perspective which can force a person into bodily harm and suicide due to feelings that people shouldn't have to cope with in the first place, let alone be able to cope with.
Another widely known psychological disorder, which can be both genetic and chemical in nature, is a disorder known as schizophrenia. In the case of schizophrenia, there is a rather large area to cover diction wise, so I'll give the basics of what I know, and see if it helps. Schizophrenia can start as neurosis, a state of heightened anxiety and nervousness, which varies as often as not. From here, it can easily be treated with counseling or medication. However, if the neurotic person begins to expose themselves to difficult situations, or, as has been proven through extensive study, the excessive use of marijuana can also affect a neurotic person and force them towards a state of schizophrenia. (I'll leave this as a base explanation as I still need to get to the point)
Schizophrenia is, most commonly, an auditory hallucination, however more severe cases can have visual and sensual hallucinations, and in some of the far off cases, complete lack of control over the ability to define "this" world from the one in which they 'perceive'. (In short schizophrenic pain would be the lack of control over one's self and all the other explanations are above as well)
A note on physical pain; physical pain, like when the skin has torn open or a bone has broken, is meant to notify the brain to an issue in the system therein. So, in the case of people with nerve issues, like a pinched nerve or so, the nerve in question would feel extremely painful and the pain would 'roll' up and down the limb, or specific area in which the nerve that is pinched or otherwise affected, and the area that the nerve is in control of would become numb over time, and eventually lose feeling completely, and in the case of severe cases in the limbs, loss of motor control or an extreme lack of dexterity is often noted.
On the note of evolution for pain, I believe that pain has evolved the way it has, for us to perceive it as vividly and explicitly as we do, because if it were not so we would simply ignore the area in question until such a time as we deemed it appropriate. Humans are not necessarily lazy, however, along with the pleasurable affects of sex, without the feeling of pleasure or pain, we would have very little to live for. Pain is learning. Pleasure is rewarding. (When I say 'along with the pleasure of sex' what I mean here is, if we, as human beings, did not have the sexual gratification that we get when we fornicate, we simply would not do it, or we would do it when it was instinctually required. Which would cause havoc to our birth rates (not that we need them any higher as is) as the human mating system is actually far more flawed than people are led to believe. Humans have one of the lowest pregnancy ratios in the animal kingdom, and the only reason we are as virulent as we are currently, is because we have the beautiful feeling of ecstasy during and after copulation)
Hope this was interesting to someone. I'm off to divine whether or not I'm as insane as people think.
