Following  breast surgery on 24/8/21  I then started letrozole on 17/9/21. The only side effect was  a mild but manageable,  although continuous headache, I then completed a course of radiotherapy with the normal early  side effects which have settled,  however the headaches have now got increasingly  worse and are accompanied by neck and shoulder pain.

my CNS has suggested that I  stop the letrozole until I see my oncologist at the end of the month. I know this is still early days but has anyone experienced this and if so did how long did it take for these debilitating headaches to reduce to being manageable.
