Oh, Jo!! Been there, done that .. also in the Canary Island (Tenerife). Unfortunately I wasn't as lucky as you to continue on as we were one day away from heading across the pond to FLL and the doctor on Celebrity was concerned about a possible blood clot because after assessing me on the ground on the pier where I fell, he was about 99.999% sure I had fractured my femur. Turns out, he was 100% correct, as was confirmed by x-rays later that night at the Tenerife hospital.
Assuming you'll be continuing on, we'll have to compare "ambulance ride" stories when we meet up on the TA. 😉 In the mean time, be careful!
