Ultracet and lower back pain

Ultracet was the best thing I have used for my lower back pain. It has given me hope of being pain free while my back heals. I know that I can get out of bed and do my daily work. I have used it on and off now for 6 months and have had no side effects, just the absence of pain.

My Dr just prescribed Ultracet for me today for intense lower back pain that developed last night. I've researched the info at Ultracet.com and all of the side effects people on here describe are side effects listed at Ultracet.com. I'm not sure I want to get this prescription filled. One side effect says it may cause anemia. I just got out of the hospital last week because of severe anemia as my Hemocrit was at 11 and I had to have 4 pints of blood (transfusions). Maybe I shouldn't take the Ultracet??? Any feedback??
