On a cursory examination of your husband’s horoscope, there are two main problems in his charts. 6 planets are conjoined in his Lagna and this creates what is known as Grahayuddha which diimishes the potency of those planets. Saturn is posted in the Eight house which is the weakest planet in his Kundali and he is running Saturn dasa starting from 2010 and till 2029 he is likely to have the type of problems you have narrated. Remedies to propitiate Saturn could do some good. Recite Varaha kavacha and Garuda dandaka daily to tide over the current difficulties.
