Query: Great, for a while

I am a larger woman with very muscular forearms - you are probably safe ordering these in terms of size in general. However... While they seemed great for about a month, my hands/arms began to cramp during the night after using them beyond those first weeks. While I cannot explain why, it is worth mentioning. For that reason, I will return to the Ace TekZone supports - the Velcro gives out after 6 months of nightly use but they work without pain.
