Hello, Welcome to Just Answer and thanks for your question. Some types of chemotherapy have peripheral neuropathy (pain, numbness) as a side effect. I'm glad the drugs you are taking are helping. There is no cure, but the problem may get a bit better over time and there are medications (such as the ones you are taking) that can help.
I'm sorry you didn't like the answer even though it is complete and true. Shame on your oncologists for not explaining possible side effects of the chemo and in not giving you literature to read about the drugs before you signed the consent papers.
