Hi undergroundbarbie,
Depending on what the spots look like this could be Keratosis pilaris. This is where the follicle gets blocked and it is also common on the tops of the arms. Exfoliation and moisturising help.
Or it could be acne type spots , but its difficult to know without seeing it. I don't think it is necessarily to do with the HRT. if its really bad , your GP may be able to give you cream to help. Unfortunately these things can spring up unexpectedly , sometimes with no explanation.
Don't be embarrassed as its more common than you think , except people don't tend to talk about it.
