Finger joint pain in morning and night

Hi I thought I make a post here about my joint pain. I am on transdermal HRT x 6 pumps a day - I know very high, but even with this, I am only just hitting 300+ estrodiol on day time blood test. It appears I have absorption issue…? Anyway… I am 36 with menopause post chemorads (completed this Feb)… I have noticed increasing amount of hand/finger joint pains and ankle pain, but largely in the morning and in the evening… the fingers feel hard to move in the morning, all locking up. Painful to move. But as soon as I wake up, 2-3 mins later, all pain are largely gone, locking stops.

I wonder if anyone else is experiencing the same… is this HRT side effect or low estrodiol or hormone imbalance…?
