Coughing, cold symptoms, congestion and sneezing for over three weeks   Is this a cold or is it allergies?  The sputum was green and now is yellow.  Do I need an antibiotic?

My 25 year old daughter has very bad excema all over her legs and now bruising is appearing as well.  She is a dance teacher and suspects maybe the fabric she wears on her legs may be the cause but cant pin point it it is so severe.  Any ideas? she is too embarrassed to wear shorts or go to the beach.  She has tried all the dietary elimination methods to no avail.  She only washes with special liquid provided by skin specialist.  Any suggestions would be helpful.

What should if I have a terrible allergic reation after being bitten by black ants?
