I had 6 treatments of Rituximab and very first treatment they found out I was allergic to it and my throat closed up and I passed out next thing I know I wake up surrounded by nurses. They promised by the next treatment they would have an allergy med to counteract reaction. Not gonna lie it scared me and made me question continuing treatment,but by the next treatment they had it right. Imagine being allergic to a medicine that saves you're life ! I have been symptom free up to two years now but am experiencing some symptoms I had prior to diagnosis now and they are running tests to see if my cancer relapsed or I developed a secondary cancer which is common with the type of cancer I have which caused my spleen to enlarge drastically. It was so enlarged I wasn't able to keep any solid food down for a year and had to have protein shakes . The only thing thY helped my nausea was the gummies I tried zofran and everything and nothing else worked. I am afraid my cancer may be back or I developed a secondary cancer because I don't have nausea but am spitting up brown thick mucus which I haven't before and just had X-rays done yesterday and doesn't show bronchitis or pneumonia so not sure whYs causing it. It gets very frustrating when Dr can't find what's wrong but you know you're body and know when something isn't right. Sucks cause I don't hAve any family left alive but I have a few friends that are very supportive. I pray everything works out for us all and we remain in remission. This is a horrible disease! May God bless you and keep you safe 🙏 feel free to add me on Facebook whoever would like to my name is Dottie Lawing 😊
