Letrozole - Is there a light in the darkness?

I'm very, very cautiously expressing hope that things may get better on Letrozole.  Some of you may know that I have been one of the unlucky ones to have very severe side effects from the AI.  Joint pain, soft tissue pain and injuries have been hugely debilitating for almost the entire time I have been on it (ticked over 2 years at the beginning of August).  Well, I hesitantly say this...  I got home from work on Thursday, got out of the car and thought, "that's weird - almost no pain".  Now this is the time of day that I am usually struggling really badly and hobbling into the house as quickly (joke) as I can to medicate.  No need to hurry.  I am still feeling that way.  And it can't be due to warm weather because it has been freezing here.  I am not abandoning the medication that has taken the edge off the pain enough to make it manageable, but I am hoping that I have turned a corner.  I have to admit that I'm also in slight state of disbelief and a bit suspicious that things could change so radically.  My oncologist said a couple of appointments ago that often after about 12-18 months pain settles down but I think we were both disappointed and resigned that this wasn't happening for me.  Given I am on this for at least 8 more years that's no minor obstacle.

I realise that it might get bad again but I can now hope that it will also get better and maybe this will also give others hope for the same.
