Do you mean a rash
around her eyebrow? right sided headache, then lumps or rash and then right sided neck pain
... please make sure she doesn't have local skin infection
or general viral infection. Keep giving her Panadol
the way you are giving. It'll take care of the pain and mild inflammation, if any, from the lump/ rash. If you see more and more such lumps appearing, do take her to a GP or dermatologist
to rule out any communicable infection. Make her aware that it should not increase and cause further trouble to herself and hence she should see the doctor personally. Eyebrow twiching must be part of the irritation. Take good care of the sugars and general health. Good Luck.
