Hi Alan,
I've just had six months on Cycloph, Dex and Velcade. My first four months were very bearable, but unless you've had chemo in the past,it's often rather alarming when you begin on a new treatment.
In the first four months the Velcade made me fatigued and I had some twinges of pain in my bones that lasted a couple of days around the times of each injection. Occasionally I got a Velcade 'headache' for twenty-four hours. It was easily treated with pain killers.
The Dex always is a bit of a problem on the withdrawal days as I have trouble walking properly and just get super weak. It passes.
The cycloph. can certainly create nausea and it helps to take the meds that have been recommended.
This does not achieve the comparison you are wondering about, but I can assure you that for some people, Velcade is not entirely side-effect free.
Good luck,
Eva
