NeuroTalk Support Groups - New here and need some help right away

Got RSD/CRPS for about 5 months now...having trouble finding dr to get diagnosed it seems so simple I have all the symptoms in order and nobody will diagnose me. I know I have it it's obvious. Don't I need to get a nerve block soon or it's possibly too late?
Some don't subscribe to the different way I got verses the vast majority. Mine was caused by an initial highly charged anxiety emotional event, then 16 days later an outbreak of shingles, then few weeks later the beginning of a 5 week gain of 31 pounds and two watermelon leg edemas, went as fast as I could to every dr I have beginning with cardio reason was couldn't walk up steps without heavy breathing and I had triple bypass 2 years ago...all the heart tests fine so the bypass workout out well, then to pulomonologist and all good all together every kind of test was normal or negative...I couldn't figure out what was going on as I thought a series of maladies after shingles were all independent events ..then I found the RSD websites and as soon asi read the symptoms I knew instantly was hand in glove...took some diuretics to reduce the edema and that's whe all the pain started at first I just thought it was because nerves were waking up, every single ligament, tendon, foot part everything below my knees both sides bilateral and the same pain in all of it...after awhile dealing with. The feet few weekends just felt the numbing tingling in finger and that's whe it moved to I have both feet and both hands..I started to get worse and worse pain I moved the unbearable line further out each time until this past Sunday...it was completely different and I can't even call it pain it was beyond anything I could imagine. At the beginning I had some strength and I just stood up to it and tried to ignore it the I called it out tried to be macho and face it down...I did for about 20 minutes, then it just continued to wear me down, I lost a lot of energy,things took longer to do,I couldn't sleep had some short term memory and hearing loss, i noticed a lot of it just following the RSD support site ...anyway I've already been through the can't believe the alternate reality I'm in..I am trying to start physical therapy this week it's too long but I couldn't walk on feet but now my arms are just fading away like toothpicks compared with what they were, I definitely lost strength and also dexterity, hand strength all across the board. Can anybody clear up for me the importance and timeliness of trying to get nerve blocks now? I don't see how my pain can be SmP in that. I had no localized trauma...just the shingles infection which must have lit up my sympathetic nerves and my other flaming factors of highly charged upstate like a tinder box ready to explode and it did...
