I have been on Calquence for 54 days. This has been a journey, for me. I am happy I took a leave from work for three months. I had several side effects, headaches, loud ringing in my ears, and I had severe muscle pain, and had a hard time walking. Some days I cried, but its is better to take a pill then Chemo. Then I caught a virus it lasted for three weeks. Today, I have to say I am feeling better. I even took a 13 min. walk. I do have anemia, which have contributed to some of these side effects. I am hoping I can return to work on Dec. 27.
