horrible pain in hand/wrist/forearm?

I moved into a new place a couple days ago. I was lifting furniture and have had to scrub down the walls and cabinets (previous tenant was a smoker) Yesterday evening my wrists and hands began to hurt. Last night I woke up about 3am in HORRIBLE PAIN. My forearms/wrists and hands hurt something terrible. The pain would come in almost cramp-like forms (burning-tingling-numbness) and no amount of flexing or bending would ease it...it would last sometimes a full minute. within 30 minutes the pain was continuous and I was in tears. I took 3 Advil and managed to fall back asleep. The pain is still pretty bad. It is in both hands (wrists) but primary in my left (I am left handed.) What the heck is wrong? Anyone have any thoughts? Should I just stay on the Advil and ice up on the wrist?
