Chest pain while meditating

I have been working with one particular exile for several months, alone, while trying to find a therapist. Finally found one. In therapy last week while working with the part, two new parts showed up. One was a bright light and the other chest pain. The therapist asked me to try and work with them in between appointments. I meditated last night (that’s how I usually work with her) and the chest pain was back with several memories that have been around (not repressed) but I’ve never really felt them before. One in particular I have memory of the trauma but not the “why”. Why my father did a certain thing … like what set him off and what he was saying at the time.

This is really the first time I have felt severe pain and it took longer than usual for this protector to unblend. Has anyone else had physical pain while working with a part?
