HI Geronimo
What is happening to you, is what happened to me as far as the delay in medical attention from WC. It took that lapse of time( 2 months) to make my pain receptors reverse into the non-stop hyper state of pain; which, in turn effected my sympathetic nervous system. My injury happened on 3/24/07. It was a simple median menicus tear (inside part of right knee). I finally had the tear repaired on 5/22/07! The burning pain, the discoloration was apparent immediately. I was ignored by the doctors and the physical therapist....
I am going to email you my story( way too long to post here) and then if you have any questions, feel free to contact me.
I hope you feel better...you need an atty., as you need adequate pain relief and you are not getting it.
