Anyone experience muscle aches on Hydrea?

I don't take Hydrea but I do experience frequent muscle aches in the mornings, so mine at least are unlikely to be related to any medication.
Against that, I am nearly 80 and well above average active for age, so my aches are probably more about trying to carry weights that were easy when I was 20.
I think the lesson from that for all of us, is to realise that the bits inside are the same age as the bits on the outside so we all need to behave accordingly.
