Dear SuseB, So sorry you are experiencing the muscular issues as well as neuropathy. I too had severe calf cramping and hand clawing and also had some issues with my lips cramping of all things.
My oncologist decided to deliver the chemo I received at the hospital at a slower rate which helped immensely. It didn't totally alleviate the cramping, but reduced it a lot. It did make for a very long day at MDA, but it was worth it. The chemo rate for the pump infusion remained the same.
I hope you get some relief!
Susan
