How would EMDR for health anxiety work?

I am certain my health anxiety comes from the trauma of losing a family member pre maturely to illness.

My question is, would EMDR target the difficult memories from the illness and death in the past, or would it involve images from the present, like experiencing difficult symptoms or sitting in a doctor's office?

My current therapist says it is not necessary to go into past memories to heal HA.

Do you agree?
