After someone has been sick . . .

A friend of mine has been sick over the last few days and I want to see if they are feeling okay now.

What is an appropriate expression to use in this instance?

I am hoping to say something a little more than 大丈夫ですか？or anything like that but I don't really know what would typically be used.

具合はどうですか？(polite, friendly)
具合はいかがですか？
お加減はいかがですか？
お加減はいかがでしょうか？
お加減はいかがでいらっしゃいますか？(honorific, formal)
