HI Angela. I am currently taking rituxan as a treatment for Waldenstroms Macroglobulinemia, I start again next week for my 4th round, I have to go every 6 months for it, I run a very high fever the night of the my treatment, and sometimes into the next day, but I have noticed since I have been on this, I have had back pains also, and I suffer fatigue, but that goes along with my cancer, other then that I have had no other problems with it, now during the treatment, I have had my BP bottom out 2 times, and they had to give me a sodium steroid to bring it back up. I am thanking God you are cancer free!!!!!!!!!!! What a true blessing that is!!! God bless you sis and I pray that you will have no more side effects from the rituxan, and I am rejoicing with you, that there is no more cancer!!!!!!!!!! Blessings, Pat
