I gather that you are new to the forum so welcome. If you are enquiring about Zoladex perhaps you are already along the treatment path! There are links available if you need them for resources https://www.bcna.org.au/resources/my-journey-kit/
As to Zoladex I have completed this treatment and my side effects were sometimes hard to decipher between Zoladex and my other medications. I had the injection alternate side of the abdomen and the month of the left side I made sure I had the couple of days clear so I could cope as it would seem to upset my metabolism. Right side I didn't have the same problems. Aching joints, a bit of bloating, were the norm. I just kept counting them down
Not sure of your age group but this link here speaks of Zoladex and it also gives you an opportunity to further research the BCNA website as well as
