Hello l to like you experienced a lot of side effects while taking vtd, l thought it was the velcade giving me my symptoms but actually think it was the thalidomide. I too was very tired, l didn’t have swelling in my legs but they were very week even to the point that l couldn’t stand for very long, if l bent down to say get something out of low cupboard l could hardly get up had to hold onto something to pull myself up. I had three cycles of treatment the good news is that after treatment stopped it wasn’t long before that tiredness changed and l got my strength back in my legs. The good news is the treatment worked really well, keep going, rest when you can and don’t feel bad for not being able to do much let your body do its magic and get better.
