What is incumbent upon a woman who fed others in lieu of fasting for three Ramadans due to a chronic illness, then completely recovered from her illness?

"Whoever is unable to fast due to an illness from which recovery is not expected, is obligated to pay the fidyah (expiatory feeding) according to the majority of scholars, and it is recommended according to the Malikis. If she recovers and becomes able to fast after having paid the fidyah, scholars have differed as to whether she must make up the missed fasts: some say yes (Malikis, Hanafis, one narration from the Hanbalis, and one view among the Shafi'is), and some say no make-up is required (Shafi'is and the relied-upon view among the Hanbalis), and this is the more preponderant opinion. It is permissible for a woman to adopt either of the two opinions, though making up the fasts is more precautionary."
