I have regional pain syndrome in right arm. Old WC injury. I was started on a new statin a week ago. Now my right arm is bluish again and in pain. I can feel cysts near my surgery site, from the ulnar entrap ment release done 13 years ago. My question is. Did a new statin start this, or this cyst problems and pain, weakness, swelling, stiff going to happen on it s own. So, does the arm need to go to Workers Compensation for review as case still open. Or do I go to doctor to see if statin and a 30 pound weight loss in 3 months started this.
