This has been a crazy road. It really stinks to be sick, unable to do things you used to do. Searching and waiting for a dxs . Getting one that fits so well. Then my dr passed away, wait for replacement dr. Comes in doesnt believe in as. States that. It is the biggest mistake to order the bl27 marker. It does nothing but cause trouble. And sits down. I'm so sorry to tell you you do not have a life altering decease . So very sorry. I believe it is all physco symatic. I had to keep seeing her for my meds and now afraid to keep searching. I went to reumatologist who suggested pain specialist. I found a new dr whom I love. I'm so amazed at the difference. Like black and white . I'm shocked.
