applying for dla whilst undergoing ib to esa

Has anyone done this and would it be a wise move. I have got worse over the last two years and pride has stopped me up to now for applying for this.

There is absolutely no reason why you cannot do this and, indeed, many people do so. DLA and ESA are two totally different benefits with different qualifying criteria.It is up to you whether you feel you have the energy to fight two battles at the same time!
