Hi IVPound
The skin biopsy is a "piece of cake". Really simple. Takes a while for the scabs to fall off. Hope you get some kind of definitive results. Mine came back negative as have all my tests but I am still burning and tingling. I am now leaning toward CRPS and wondering about you too since yours started with the blood clot. Mine slowly evolved after an auto accident in my left arms but now pretty much all over. Still, bottom line nothing much helps. I am debating on starting Cymbalta after the first of the year...waited to get thru the holidays first. Anyhow, hope you are feeling better soon...all of us for that matter. I have started all of the mrs. D supplements too but so far nothing has shown improvement but maybe takes a while. My B12, methysomething and Vitamin D are all in the good to normal ranges. All other numerous tests have been fine.
