hi, i`ve had surgery on broken ankle, trimalleolis, have 3 screws & a plate in my right ankle, its my 2nd week of wearing a fibreglass cast & i`m having fluttering & warm squirting sensations when my foot is elevated. i`m soo worried that my cast is too tight, cos my toes turn purple when i`m up on my crutches just to use the bathroom. I`m scared cos i dont know whats happening, very little advice from doctor in hospital, hope you can help? oh my name is Olivia, from Ireland. thank you.
