I see your question was posted almost 2 weeks ago - how did things turn out?

If it were me, I'd call my pediatrician or go to the ER.  That sounds like it could be a serious allergy ... but you won't know until someone checks it out.  My daughter would get fussy if I ate cabbage rolls or spaghetti sauce, but this sounds different.  Is he calm to the point of lethargic? or normal.   On the other hand, my sister (A year younger, so she wasn't a baby at the time) used to get hives regularly, but not all over, and they never did find out what it was.  She was rather 'hyper' as well, and maybe it was emotional.  But a baby can't tell you how he feels, please check with your doctor...
