You sure have been through a lot! I'm so happy you are a survivor. I'm sure everything has the ability to make you very worried. It's a nightmare and a beautiful dream to survive cancer, I'm sure. But you did! And your oncologist is really in a position to know if you need worry or not. That they aren't worried is a very good sign. They treat many patients similar to yourself and know warning signs. They know too that some do get the nerve pain she says this is. You've had marker tests? I'm sure they are following you closely for recurrence. Neuropathy is common after chemo. The tests they usually order for peripheral neuropathy are :
electromyography, nerve conduction studies, and quantitative sensory tests to further examine peripheral nerve function
laboratory tests to look for metabolic disturbances and nutritional deficiencies
imaging tests to look for other possible causes of nerve damage
Many cancer centers have integrative medicine specialists to work on treating this.
