Decapeptyl has stopped working?

[ANK1173]

Hi all. I have been having monthly decapeptyl injections since the summer and my Consultant has said he would like me to stay on them for as long as possible. I am also taking Indivina HRT. I am due my next injection on Wednesday. For the past few days I have had that familiar gnawing burning pain on the left side. For the first few months on decapeptyl I was pretty much pain free so the side effects were a small price to pay. Can it just stop working? Hope everybody is as ok as possible. Thanks. Ax
