I have a question regarding the latest reports of my dad. He was diagnosed in September 2010 and ever since he has improved drastically and his ratio number came down to around 4. The normal range I believe is 0 to 2.63 or something similar. But in his latest report after 6 weeks of chemo(twice a week) his ratio increased to around 5. It was a 0.6 increase, is this normal?? Does it go up and down when it gets to low numbers?? Also how long does it usually take to get into normal numbers?? By the way have any of you experienced tingling sensation because of chemo?? How do you help that?? Another thing I want to know, is there a way of telling how aggressive the myeloma is??
Thanks a lot guys.

I'm only 17 and don't understand this much as of now. I research on it everyday!!
