Dr. says these have something in common. l.l. abd. tenderness, esr29mm, proteinuria, low back pain, ear blocked, edema, vit.d deficient. whatcould it be?

Doubt common link: I would ignore the sed rate of 29. Vitamin d deficiency is rampant in the developed world and you are hopefully being treated. How heavy your protinuria is might have to do with your edema -- do you have nephrotic-range proteinuria? I would doubt any connection to your low back pain if it's not actually kidney pain, or to whatever is blocking your ear. Good luck -- hope this is manageable.
