I'm glad you're getting it figured out GLM! I have been allergic to something (solution, dialyzer, I'm not sure) for 7 years, and no one was willing to investigate. They just gave me Benadryl, which I hated because it makes you so sleepy and my body actually became addicted to it for a long time. Anyway, I recently moved back to my hometown where a new dialysis unit was built. The manager of the unit is AMAZING, she actually listens instead of trying to drug you up! We have the new special dialyzers on order, hoping they will get here soon and hoping they will work for me so I can stop itching and feeling icky!!
