I had an asthma attack then when i recovered i had an outbreak of hives it's the 3rd day now. i'm breastfeeding?

Puzzling pattern: Hives often represent an allergic response to an ingested food or drink. In some this can also trigger an asthma event. If you can think back to a novel food /seasoning/drink it may be the trigger. The duration of the hives will often match the several days it takes to digest/process the food item and expel the residual from the body.
