Hi,
Mercury/Budha is strongly placed in the 3rd house of Communication. In my humble opinion, the problem or issue is elsewhere, other than Mercury/Budha being posited in the Lunar Constellation of Saturn/Shani-dev who co-rules the 6th house of Roga-Sthana, along with Rahu and making the primary contributors to the stated situation.
In any case, offering special prayers to Shri Lakshmi Narasimha Swamy… is essentially seeking divine grace/blessing for relief from Saturn/Shani-dev (and perhaps Rahu as well), Mercury/Budha and Venus/Shukra.
Take care…
