Bad numbness and tingling from shoulder area to fingers both sides, 4days now worse when i sit but constant. go to doc or er? no injury,fibromyalgia

I vote doctor: ERs are costly, risky and less helpful for many things. W/ your list of conditions and medications, your best choice is your own Dr. They'll check to see if your chronic conditions have worsened - hopefully find good Tx. Consider a Health Psychologist for support and help dealing w/ chronic, serious illness. Aso, read: http://patienteducation.stanford.edu/programs/cdsmp.html
