What Is The Treatment For Difficult Breathing And Pain In Shoulders?

i have had a mild heart attach 10 years ago and now im 43. I m on painkillers as I had a bad accident a few years back. A few days ago I has very stupidly lost my pills on a family outing. Been dealing with withdrawls since. Now today I tried to get out of bed and hurt so bad I could barley move. I quickly found out that breathing was nearly impossible, can NOT take a deep breath at all. I have also noticed now that my shoulder is in extreme pain with even the slightest movement. The amount of pain in beyond anything ive experienced before. And I have went through withdrawals before. This seems different. I ve already went through the puking and shits and flu symptoms. I feel like I m dying. I can t breath, the harder i try the worse it gets this has been going on for about 6 hours with no let up. what do i do. I don t want to take the risk of e/r cause ive been told ill loose my script, and god know i cant survive without it. But right now still feels like sword through my chest shoulder and ribs
