Legs giving out after waxing

hello y'all I just recently went to my monthly Brazilian appointment and upon finishing and getting off the table my legs suddenly went numb! I couldn't feel any pins and needles as if they were asleep, I just couldn't feel them at all. So when I jumped down from the table my legs gave out underneath me. I've never had this happen before in my three years of waxing and it was so odd to experience. it only lasted a minute and I was completely fine afterwards just a bit embarrassed lol. Has this ever happened to any of y'all? I'm assuming it has something to do with circulation while my legs were kept in the butterfly position.
