Welcome to the world of drug abuse! I still have lung, heart and major sinus problems and I've been clean of that stuff for over 4 years!
You will feel better.. I enhaled a couple drops of eucalyptus oil in a cup of boiling water a few times a day and it really helped heal my lungs and cleared my sinuses as well. Remember to exhale really deeply a few times a day too. I don't know what to advise about the heart stuff.. I still suffer from irregular heart beat but all my doctors have told me that it goes hand in hand with cocaine use and also with pot.
