I am a physical therapist. I met with a new patient today who was in a plane crash in 2010. She had cervical trauma with a herniated disc and compression fractures. She has had ongoing neck pain and just over 2 months ago started getting peripheral edema. She said she first noticed it in the right hand, then the left and then it progressed to the feet. She now has it in all 4 extremities accompanied by strong pain ( especially in the hands) and decreased grip strentgh with difficulty making a tight fist. Could the peripheral edema possibly be a result of the cervical trauma. Even though it occurred over 3 years ago?
