Hi and welcome to MM
Aches and pains are all part of ageing I'm afraid. Probably nothing to do with the HRT but some exercises might help. If flushes are under control with this HRT and it's suiting you generally, then it's worth looking at other lifestyle choices to see if there is anything you could improve. Are you taking Omega 3 oils and vitamin D? Vitamin D deficiency brings fatigue and aching joints! We've had precise little sunshines for so long now, so we all need some Vitamin D supplements. You may have a bit of arthritis - talk to you GP or a physiotherapist. Dg x
