Rituxan Reaction Continues

I am 3 days in to my Rituxan dosing and have yet to stop with the reactions. I have severe shortness of breath, rheumatoid pain and swelling in the hands, knees, and feet. My breath is so short, I am not able to speak on the phone in conversation. I had to draw a picture today of what I wanted at the store, because I could not "describe" it in speech without feeling like I was running in a marathon. Fortunately, Tom understood my drawing! I have been in contact with my doctor, she is aware and very supportive. I have promised her if I feel as if I need to go to ER, I will. We are trying benedryl for the next 72 hours. I am blogging and documenting this, so as to help others with Rituxan reactions and or treatment. I ask and ask those who have taken Rituxan, please share your experience. There is such a lack of information on this topic in RA world. I would really like to change that for the next person who has to take the medication. It is frustrating to feel alone in this medication treatment choice. I do know this, everything I have been able to read, has been positive. If I can just make it through these side effects, the potential of this medication truly helping has good possibilities for me. My next infusion is April 30. The doctor has already started planning to pre medicate me before I leave the house with benedryl, steroid, and Tylenol. So, once again, I ask... Please share your experiences. Thank you for your help... Kim
