Hi I have 2 tumours 1 in my spine and the other in my chest bone , I have been on letrzole for 5 yrs up till 2 weeks ago when I was told it is not working anymore so consultant has changed me to verzenios tablets and injections . I take 2 tablets a day and have 1 injection every 4 weeks along side my denusab injection. I can't really say I have lots os side effects but the one I have is so awful. I get terrible cramping in my stomach then either wind or diorahha . I was wondering if any one is on these tablets and suffer with these side efffects. If so have you any way to help my get over this . The cramps are so bad I have even thought about comimg off the tablets .TIa
