I m not feeling well. I have a chronic pain that is between my ribs on the left side that is being treated with long term opioids, changed one month ago from butrans to oxycontin becuase i started breaking out in a rash at the patch site. My blood pressure is 143/97, HR 60 s -70 s, O2 sats in the high 90 s, temp 97.8, resp low teens. I have been hurting more today when i take a deep breath and on the left sife of my head and back of my neck. I am nauseated and feel like my heart is fluttering. How concerned should i be? I do have a history or cardiac effusion r/t steroids, but am currently not taking steroids.
