I was sorry to read about your Mum - I hope that she is recovering well from her treatment .

Nucleolar/speckled ANA patterns can indicate both scleroderma (which seems to have been ruled out) and polymyositis.

Polymyositis comes in many forms. One, called dermatomyositis, includes blue-purple discolouration on the upper eyelids as a clinical sign. This fits with (your words) "my eyelids are purple".

There is some information about the various forms of polymyositis here; Myositis - Polymyositis and Dermatomyositis. Information | Patient.
