Unexplained blue marks

Dear Doctor
My 8 year son had chicken pox in April this year. Shortly afterwards I noticed a blue mark on his back but did not pay much attention. Recently I noticed the exact same size blue marks on the other side of his back and that both marks are now rapidly spreading. Its not red nor is it itchin so my GP recommended blood test and the results were all negative e.g. bleeding, anemic and bleeding tests. He said I have nothing to worry about and that it just might be an allergic reaction. My motherly instinct tell me I should worry and there''s no improvement. Should I go for a second opinion? Please advise soonest.

What is needed here is a clear diagnosis of your son's condition.This is not the usual way that chicken pox scars behave.In particular there is a illness seen in children called 'mastocytosis' caused by the presence of too many mast cells in the skin that needs to be excluded here. Your son should be seen by a dermatologist as soon as possible.Ask about possible mastocytosis when you see the dermatologist.
