First, thank you all so much for your messages and concern. I checked her again at lunch time and the swelling is down to about half what it was and the bright purple discoloration is fading a bit. So, some improvement.
I did call 811 which is a NS Health line that connects you to a nurse. Her advice was to continue what we are doing and monitor and keep pumping her with fluids to try and flush her system. Unless things take a dramatic turn, I am not doing the ER thing again. I softened the actual experience in my last post. It was enough to make your hair curl!
Another positive - we found a man to shovel the kitchen/pantry roof. He came this morning and did a great job. It cost $75 but was worth it for our peace of mind. He even took up a bag of salt and ice melt and sprinkled it along the eaves. One less thing on my mind. YIPPEE
