I finished 12 treatments of FOLFOX for stage II colon cancer six weeks ago. The side effects in my hands are getting so bad. When I wake up in the morning I cannot bend my fingers, this has only been for the past two weeks, my feet are numb and my fingertips tingle all the time. The thing that is worrying me the most though is the pain in my finger joints. Has anybody else experienced this? I had no side effects during the treatment. I am getting really afraid of this.
