Painful Muscle Cramps Throughout Body During R-chop Chemotherapy. Stopped After Leaving Out Vincristine. Cramps Caused By Vincristine?

I ve been experiencing a substantially increaed frequency of painful muscle cramps in various parts of my body (i.e., almost daily) since I began R-Chop chemoterapy for Stage 2 Lymphoma last September. Consequently, on the sixth and last treatment I had six days ago, the Oncologist in charge left out the component of R-Chop called Vincristine . She did this because she thought it was the only component of R-Chop that could possibly cause muscle cramps and, at the same time, was the least important doe chemotherapy . Since then, I haven t experienced a single muscle cramp. Do you think this provide(s strong evidence that Vincristine was the cause of my muscle cramps? Is there proof that Vicristine does, in fact, cause muscle cramps?
