This doctor does not have your best interest at heart. Its the insurance company's best interest at heart here. When WC is involved its always a hassle for the patient most times, especially when a chronic condition is involved.

Suddenly the doctors get stupid. I've seen this behavior with my own eyes pertaining to my wife who has RSD. Example, doctor is clueless to your condition----his next patient who has RSD is covered by BC/BS PPO, here in the doctor does everything to treat the patient and their concerns. Next patient has HMO coverage, and RSD----again, clueless with the patient.

As Helpless stated, start looking at hiring an attorney.
