Thanks birchlake & everyone else,

One CRPS specialist said he wanted to try pain reliving patches for two weeks to see how they did. He said i don't meet all the symptoms of CRPS. I had another appointment the next day with another specialist and he diagnosed it as CRPS and recommended the Lumber nerve block + some medication. I'm going to wait out the two weeks and see how things develop. about 95% confident it is CRPS but the good news is that while spreading seems a matter of time, they have really good confidence the pain wont increase. As the pain is almost non-existent at the moment, this is something to be thankful for.
