Welcome to the forum. You are definetley in the right place. Unfortunately, you can not walk this out. RSD is truly a monster. Fast intervention is important. You definetley should be getting blocks from a pain management dr.
I would also recommend you get an attorney fast. WC is out for them and your employer. They are known to deny treatment and cause more pain then what we need. Also this will help a little bit with the stress that causes flares.
Feel free to ask questions, rant, rave, etc.
