Has anyone taking Letrozole had coccyx pain? It's come on strong and hard in the last two days. It renders me momentarily completely immobile when I try to move from a sitting position I've been in for a while. It was very embarrassing at the plastic surgeon's today. I went to get up and couldn't. He and the nurse stood and watched as I mumbled excuses and persuaded my body to work. I think they were as shocked as I was.
I haven't read any mention of coccyx problems here. Is it the Letrozole or have I got something else going on?
