Is there such a thing as effectively massaging yourself? Or do you mean that your partner went to masseuse school while you developed a habit of running? :p
Yes, there is. Obviously, it's difficult to massage everything, but there's a lot you can do. Especially if you have long arms or especially flexible.
In fact, you may be able to do MORE than a massage therapist can do in many parts of the body because you're always around and you only have one patient to deal with. And, while you are not as objective, you do know how everything feels.
I took an intro to massage class and have done quite a bit of reading on the topic.
