In my book, it means you did it right, at least to get strenght increase.
Right now, I can barely climb down stair, and it tells me my squat workout two days ago was just right : no tendon pain, no localised sharp muscle pain, just muscles who refuse to work and to strech.
Two day ago, I was feeling the same about my biceps, and was disapointed that my lats where not feeling the same, telling me I need to be more intense working on them next time.
But, as I'm more an athlete than a bodubuilder, I'm biased toward increasing strenght and power over muscle size.
If your goal is to get big, you still need by period that kind of intensity, to develop enough strength base on which you can then do more lower intensity muscle grow work.
