Kama,
It sounds like your treatment plan is about the same as mine; I did 12 infusions of r-abvd over six months.
I got numbness at about the same time that you have developed yours, if I recall correctly (that is, around infusion two or three). Everyone's experiences differ, but unfortunately, my neuropathy (the term for the numbness) has not gotten any better seven months after ending treatment (my last treatment was in mid-January).
My neuropathy is mostly in my feet, but affected my hands a little as well, and it does impair my ability to turn pages in a book or newspaper, for instance. My feet are the bad part, however, with numbness at times rising above my knees. At the worst, I felt like I was walking on pegs or stilts, and it affected my balance a little. I had a nurse tell me that she has seen numbness go as high as the waist.
I never got to where I could not feel my feet at all, although this happens to some people. I could always feel a pin *****, for instance.
The neuropathy is caused by the vinblastine (the "v" in "abvd"). The drug sometimes kills the protective lining around the nerve endings, which causes the numbness. Some people describe it as "pain," but to me it just feels like the numbness when your feet are "asleep" from no blood flow. Mine worsens with activity at times, and at other times, it can be bad even after sitting in a chair for a long period.
Some people get over this, and some do not. Some do not experience numbness at all, so there is a wide range of reactions. The numbness can be permanent.
I am in a clinical trial now for a cream to determine whether it works on neuropathy or not, and that is part of how I have come to study it in some detail. So far, I guess I am using a placebo, since there has been no improvement for me thus far.
There are drugs already FDA approved for neuropathy, but they treat the symptoms, not the cause, and they are not used to achieve a cure.
I hope that you do not get it as badly as I have had it, and let me stress that most people (I am told) who develope neuropathy get feeling gradually back, over time.
Keep in touch, and I am sure that others here may have more information than I have provided.
