Food allergy (yam, quinoa or cuttlefish)? 16 Mar 2008

When I woke up this morning (16th march 2008), I found about 10 red dots looked like pimples on the left of my abdomen just below the ribs but not itchy.

Is this condition due to the quinoa or yam or cuttlefish in the Hay mee (Prawn noodle, although I did not take the prawns) taken yesterday?
