I was on letrozole; it felt as though someone was driving red hot pokers through my right knee. I couldn't lie down to sleep because of hip and joint pain. After six weeks, I was so ill from lack of sleep and fatigue induced migraine my Oncologist was ready to admit me. Told her I couldn't take any more pain & agreed I stop taking it; we'd try something else once the letrozole was 'flushed' out of my system. 10 days later I was in Spain walking the Camino, no problems, other than the expected blisters and muscle aches! I'm now taking exemestane (Aromasin brand name) for the last two weeks and so far so good. Some side effects, hot flashes, waking at night. But nothing compared to the pain I was in before.
