Red Bumps on lower body?

Red bumps all over my body for less than a minute ?

• I just got back from eating Chinese food. Grouper, mango, etc. When I got home about 15 min or so later I started feeling pins all throughout my skin from the waist up. this lasted about 30 seconds and it felt like heat was taking over my body. It was uncomfortable but not that painful. Then.. when the pin feeling want away I lifted up my shirt and I was covered in red bumps. the bumps went away after about 25 seconds and there were little tiny skin-colored bumps that looked like smooth humps of skin left where the red bumps were... but these bumps were really tiny. maybe 1/3 of a centimeter in diameter.... after about 70 seconds those went away, nothing has happened since. I'm not allergic to anything that I know off, Poison oak doesn't even effect me. I eat mango and grouper all the time and nothing has happened before... What could this be?

• Answer:

  You are allergic to one or both. Go again and see if the same thing happens.
