I was wondering something similar regarding exercise. I just climbed Mt Fuji Yesterday. It's been a full 24 hours since I finished. I'm stretched, a little sore but not that bad. Today is one of the last days I can get a tattoo started before I leave. Any potential damage or reasons why I shouldn't get a tattoo done on my lower leg? Are the muscles swollen that long after exercise to make a difference in the outcome of the tattoo? I know it will likely be more painful and that's a consideration, but not a deal breaker. I just want to know if throws off the size and color of the tattoo or even quality of color. Thanks.
