Diaphragmic Endometriosis?

so i haven’t been diagnosed officially with endo, but two doctors “suspect” it’s what i could be experiencing (none will or ever have referred me forward for it though 😐).

i have googled symptoms (not always a good idea) because my period pain is not like usual pain. it travels throughout my body in sharp, aching, and vividly deep cramping. i notice it especially in my chest on the left upper side, the side of my neck, and my abdomen. my flow is always SO heavy when i get my period, so i’m trying birth control again soon to try and monitor it and see if it helps.

i know diaphragmic endo is rare, but could this be a possibility? has anyone experienced the pain i’m trying to describe or this type of endo? it’s horrible. scary feeling. makes me feel like i may have a heart attack or something. :/
