Your husband is passing through a difficult period as Ketu is in the lagan in his transit chart. Also, he is passing through Shani Sade satti period. He needs to do the following remedies for health gains during this period.
1. Read Hanuman Chalisa daily
2. Visit Shani temple every Saturday evening
3. Light a diya under peepal tree.
