Isha, the major numbers 3 and 5 of your name certainly provide support for a career as a playback singer (and similar professions).

The 3 is a number of creativity and social interaction. The 5 is a number of new experiences.

Your birth date number 1 also helps, providing initiative and self reliance to your life path.

Successful playback singing of course requires training and practice and the physical ability to accomplish the required actions. The way I read your numerology profile, it supports your actions.

Health questions may better be answered by a health professional.
