hes 7 yo and has had a cold that involved sore throat, low grade temp and a rash all over his body. I figured fifths disease because in the last couple of days the rash turned into the lacy appearance. He had a lump when this illness started on the left side of his neck but he said at the time it wasnt sore. Prolly found it around thurs, fri last week. today its larger and sore, but then he also still has nasel congestion and still has a low grade temp. I've been tx with tylenol and ibuprophen alternating. the lump just worries me since its been over 3 days.
