Posted on 29 Nov 2012: "Pain in rib cage, lower back pain, tingling bones, limbs falling asleep. What could this be?"

Please tell this person I have all of these things, and turned out to have both monoclonal gammopathy and limited systemic sclerosis (anticentromere type). To start testing for the latter, he should have an Antinuclear antibodies test, and the lab should be asked to do it by the IFE method, because the default multiplex method gives false negatives in scleroderma patients 43% of the time. To test for the former, he'll nee an immunofixation and electrophoresis testing of blood.
