Is this normal?

When I first started taking Tamoxifen I had trouble sleeping,hot flushes,low mood,forgetful.My ocologist put me on a very low dose antidepressant called Endep 10mg. It helped with all of the above but probably made the forgetfulness and lack of concentration a little worse.These are all menopause symtoms too so it's hard to know if chemo has caused this or if it's entirely Tamoxifen or abit of all 3! In anycase,you should really talk to your gp or oncologist- don't just put up with it. My mastectomy scar is very tight(done in 2010) -feels like I have duck tape across my chest.My surgeon says it's adhesions and not much can be done.Perhaps see a physio about your neck and back?               Tonya xx
