Hi, Susan. Chemo-induced peripheral neuropathy is a real thing, especially if you were given a taxane. Anastrozole can give you arthralgia, but I can't see why it would give you neuropathy. There are plenty of other things which can cause neuropathy, however, including being pre-diabetic and diabetic, too much vitamin B6, the antibiotic Cipro, HIV, syphilis, etc. I would recommend seeing a good neurologist who would be willing to test you for any underlying cause, if your chemo is not the culprit. Best of luck, and hang in there!
