I have gone through two series of chemotherapy by infusion and I am now on Tarceva. Shortly after I was diagnosed with stage 4 NSCLC in March of 2007, I started chemotherapy in May of that year. I noticed after a while that I had some numbness from time to time on the right side of my body in the waiste area; and still do at times. Towards the end of last year, I noticed a stiffness in the right lung area (that's where I have the cancer) from time to time. Since the beginning of this year , I have had discomfort and sometimes pain in the rib cage area and my back; and at times waking me from a sound sleep. Recently I stumbled upon an article on paraneoplastic peripheral neuropathy; and on the list of chemo drugs that could bring this ailment on, was two of the drugs I received in my first round of chemotherapy being, carboplatin and taxol. I was wondering if anyone has experienced the discomforts and pain I feel from time to time in the same areas I am experiencing these sensations in. The article that refered to neuropathy, it only addressed the hands and feet, of which I haven't had discomfort, numbness or pain in those areas. The cancer has spread into some of my ribs and spine, so I don't know if the discomforts I feel is from the cancer, or may be from neuropathy.
