I feel silly to ask, but what is a slice tray? Maybe I have one but we just call it something different in the States?
Husband diagnosed with AS in '92. Enbrel appx 2011- March 2013 when ER doctor temporarily terminated. Grateful to have finally found Kickas in April 2013 and NSD since May 2013. Since NSD no need to resume Enbrel. Enbrel only helped hip pain, did not touch chest pain. Since NSD, both hip and chest pain have improved. Still takes pain and other pills daily, but far fewer.
