LG is 18 months and been unwell with a cold/virus thing past few days (runny nose, sweats, tearful, sleepy, heavy eyes) but other than that has been okay.
She has had a small circle rash on her upper arm for months that I assumed was some kind of eczema (although cream hasn't made a difference. Since she's been run down, this rash area has developed a white lump over this rash. What could this be? No idea what to do
