How a sick person keeps Shiva-Keeping Shiva after being healed:[1] If one is sick, and is unable to keep Shiva properly, some Poskim[2] rule that he is to keep Shiva after he is healed. Other Poskim[3], however, rule he is to keep whatever customs of Shiva he is able, and is not required to make up the Shiva after he is healed. Others[4] rule that even if he was not in his right mind, and did not keep any aspect of Shiva, he is nevertheless not required to keep Shiva after he is healed, even within Shloshim. [Practically, one may be lenient like the second opinion, that if some aspects of Aveilus were kept he is not required to make up the Shiva.[5] If, however, he did not keep any aspect of Aveilus, such as he was unconscious, or was not told of the death, then he is to keep Shiva upon being healed and discovering the death, if it is still within thirty days of the burial.[6]]
