I have CRPS type II resulting from a venipuncture injury to the sensory branch of the radial nerve in my right arm that occurred over 3 years ago. The symptoms spread to my upper arm, neck and head after 10 months, then to the rest of the right half of my body 2.5 years after the injury. Cold sensations & cold sensitivity are a significant part of my symptoms.

PLEASE go see a neurologist that specializes in CRPS/peripheral nerve injuries as soon as possible. Even if your symptoms are fairly mild now, they could get worse without treatment. The faster you get treatment, the better. If there is a pain clinic available through your insurance, have the neurologist refer you there as well.

Also, just in case you need documentation of the injury at a later date, sit down right now and write out exactly what happened to the best of your recollection. Include any information related to medical treatment you have recieved for this, and any correspondence you have had with anyone at the facility where the injury occurred. Summarize your symptoms at the time of the injury, and where they are at right now. Six months from now, if you need this detailed information, you won't be able to remember it as clearly as you do now, so get it on paper ASAP.

Good luck!
