It is nice to meet you. I am truly sorry for your diagnosis. Crps is different in everyone. Early diagnosis key and so is aggressive treatment. As with everything the more you know the better decisions you will make. As far as your life being affected it is a given. Do your best to stay as active and normal as you can. I know it is easier said than done. You will learn what you can and can not do and then you will adjust. It takes time it does not happen over night. Unfortunately CRPS does spread, with me it seems like it spread quickly. In some people it spreads quickly and some I read that it takes a while. There are a lot of wonderful people here that know more than me. I am still relatively young in this. I fell back Dec. and was diagnosed in March. Ask questions here and someone will be along to help offer some suggestions. I wish you the best in your decision to do the nerve block or not. Again the more you know the better decisions you will make.
