Hi, Mat71. To my knowledge, AIs are not what caused your neuropathy. If you had chemo before starting on an AI, especially if you were treated with a taxane (like Taxol), it can cause neuropathy. AIs simply reduce circulating estrogen. They can give you insomnia, bone thinning, weight gain (or loss), dizziness, nausea, etc. (or not)... but not nerve damage.

You say that you are taking a B-Complex. As supplements are not regulated, you never can be sure if the dosage is accurate. Get your B-6 blood level checked regularly as too much circulating B-6 can cause nerve damage, even though B vitamins are water soluble. There are also perhaps 6-8 other underlying causes for neuropathy for which your doctor can test you (like for diabetes.

Best of luck in solving this miserable neuropathy.
