Can a shellfish allergy just be a facial rash?

[Jujube]

I had a baby 3 weeks ago, and I think I might have developed new allergies after delivery.

I am not sure what caused this, but I developed a hive on my face late Saturday night, and slowly a rash developed over my face the next couple of days. I look AWFUL (kind of like poison ivy without the puss).

I used benadryl to relieve the itching on Monday, and went to the MD yesterday who told me to take Claritin. So I did. I ate dinner (of Shrimp, which I had on Saturday night too...). At 12 PM my face was on FIRE! Itching, more bumps, more swelling.

I have NO other symptoms. But the claritin is NOT helping the itching.

Can you have a food/shellfish allergy without any other symptoms (no nausea, throat itching/swelling, etc.)?

i think it may be some thing else. try having a test done. also, i do not think that if it is fish thats the cause it should be ristricked to ur face. see a doctor again
