Welcome to Workman's Comp, aka "The Organization from Hell that will dedicate their lives to screwing up yours". I have been playing their game for over a year so I know how you feel.
When I had my IME, he also agreed with the diagnosis & treatment, then put that I could return to work anyways. That's what they get paid for. Luckily for me, I had my PM doctor write my off work slips for a month at a time. I learned the hard way, as you did, that if you miss one day with those slips, they will cut you off until you get it to them. My old Doc used to do it a week at a time only, so I ran into this problem multiple times. Luckily(?) for me now, I just got approved for Social Security Disability so I dont have to send anymore of those stupid notes
Sorry that you have to go through this, I feel for you - really. Try talking to your Doc about a monthly script, it makes life much easier.
Its funny about the PT issue - I got called once by my adjuster who proceeded to chew me out for missing a PT session. Problem was that my initial PT sessions had been used up and the adjuster had not authorized more yet so therefore I didn't have any appointments scheduled - a fact that the PT manager was happy enough to slap back in the adjuster's face.
My advice to you:
Document EVERYTHING. I refuse to even speak with my adjuster on the phone, Email only so I have record of every conversation.
As stated, ask your doc for monthly scripts for off work status - its not like you are going to all of a sudden wake up tomorrow with no RSD...
Do everything they tell you to (as long as your Attorney OK's it), they will look for ANY reason to stop paying by saying you are refusing to cooperate. I have received about 5 different Dispute Notices due to little things like changing a Dr. Appointment without notifying them, missing a PT day due to getting the Flu, etc.
If you have not yet spoken to an Attorney, DO IT NOW! Find one in your area who knows what RSD is - you will need him eventually. You may be missing out on other money that they will not voluntarily pay you. (another $270 per month for me)
Keep your chin up - take life day by day so you dont go insane. I know your pain, and sometimes it can overwhelm you. Don't let it - Vent Here with those of us who understand.
Research RSD/CRPS until you get tired of doing it, then do it some more. Knowledge is power.
Get ready to file for Social Security Disability - talk to your lawyer about the timing with that. Even though RSD is not a listed ailment for SSD, you CAN still get it. Same goes for age - I am only 39 years old.
Good luck, I wish you the best!
