@nicoleny A few things. Probability of multiple organs and tissues involved. Pancreas 4/9. Slow growth of problems. Left side pain. And just guessing that your sFLC(C) will be toward the high side, but not over the top. Then when you you take it again in another year or so, it will be a little higher for the kappa light chain protein. Then it will continue to develop, but you will watch it grow another year or two, and do the sFLC again. You probably have developing liver non-alcoholic Fibrosis. Mine is stage 4.
