Hi. Welcome. Its a shame you have to be here but its good you are here.

I also had some pn from a burn injury. My deepest burn was over the metacarples of my left hand and it very quickly turned to CRPS. my burns were 7 months ago.
I can honestly say knowledge is power. Do lots of reading but dont get caught up in the horror stories. Because your at the early stages you have a chance of remission so educate yourself on how to best aim for that. Dont just look at medical treatments. there are lots of other things you can do. Epsom salt baths are great and Physical therapy is recomended. This forum is full of information so read back over the posts and also look at the recomended sites in the sticky notes.
On other thing that was a must for me is a "use it or loose it" attitude. At first i was advised to have complete rest but by doing that i lost movement in hy hand. Big mistake. I started to use my hand just a ittle and then rest it and start over. in time i have regained movement and my hand has improved in this area. your PH will help you with this.
