Even with the measures you've indicated, there's no guarantee that the cramps will stop. Cramping is not well understood. It's not simply caused by low potassium, sodium, or electrolytes. Those may certainly affect cramping, but, there are other factors involved, some of which, are not fully understood. Age, prior injury, and, recovery ability can certainly play a role in the severity and frequency of cramps. You should try to record the circumstances that may have resulted in your cramping (even if only making a mental note) when it occurs. Later, if you have another episode you can refer to your notes to try and figure it out. I've been troubled by calf cramps in only one leg. I've started to build some anecdotal evidence that it may have something to do with consuming caffeine before a training session. Stretching has helped, but, they persist with no rhyme or reason that I can tell as yet.
