Question:
I had a tooth pulled on Eruv Shabbos and the dentist advised me to use an ice pack on Shabbos to keep the swelling down
He provided me with a freezer pack with water inside which i must freeze on Shabbos and then take out to apply to my jaw to keep the swelling down
Is this permissable?
Answer:
There is controversy if it is permitted to make ice cubes on Shabbos. If however it is a big need for it on Shabbos numerous poskim permit it. If you need the ice to reduce swelling, that would be considered a big need.
Best wishes
