RSD Face going numb

I hurt my right knee had surgery and was told I have RSD 3yrs ago.  My RSD has spread to left leg I get lesions, low fever allot of pain. New symptom: I am always out of breath and my left side of my face is tingling and has numbness.  I wake up in pain about 9 and my heart feels like its  pounding out of my chest, chest feels tight scares me Im going to have a stroke.  I am on 100mg Fentanyl patch every 2 days, hydroco/apap 10-500, Soma, (they also gave me Fentora pills but  Im to scared to take).  My pain is getting worse no matter how much meds I take.  It feels like I have the flu all the time achy all over. That’s why I was given the Fentora to take with the patch but I don’t want to take too much. My left side hurts worse than my right. Please advice is this RSD? Also my kidney test was above normal it said pre retinal failure I need to take something other than hydrocodene. Norco makes me tired and oxecottin makes me feel funny.  So my questions are what else can I take and is the face tingling and numbness heart pounding, breathing difficulty RSD ? I have been on all of this medication for two years.  6mths ago changes patch from 3 days to 2 days. Thank you.
