Fourteen Israeli Sephardic rabbis have ruled that video-seders are acceptable during a pandemic. They based their ruling on the fact that halacha allows treating sick people on Shabbat even if their illness is not life-threatening.
My question is: How far can you go in treating non-life-threatening illnesses on Shabbat or Yom Tov? Must there be pain involved? Just discomfort? Psychological too? What are the limits? I would like to see a halachic discussion of where to place the dividing line.
(No need to downvote if you disagree with the ruling. That is not my question.)
