I’m sorry you’re going through so much discomfort with carpal tunnel syndrome, @Curlywurly1.
Although it’s not specific to anastrozole, you may find this previous thread on the forum about dealing with carpal tunnel syndrome useful: Pain in hands - Going through breast cancer treatment / Hormone therapy - Breast Cancer Now forum.
Have you spoken to one of our nurses before? They’re here to chat this through with you if you’d like. You can get in touch with them here on the forum on the Ask our Nurses your questions board or on our helpline 0808 800 6000 which is open Monday to Friday 9am-4pm and 9am-1pm Saturday.
In the meantime, I hope someone on the forum will have an experience they can share with you.
Sending our warmest
