does anyone know about fish/shellfish intolerance?

[kissmummy]

I used to love prawns, sushi etc, but ever since having my DS (now two) i've had dreadful indigestion after eating any of those things (and crayfish and shrimps.) Now i've started getting the same horrible indigestion type symptoms after eating other types of fish. (seabass, usually.) i'm gutted - i love all these foods and of course they're really healthy, but it's not worth the pain. And i'm wondering what next i'm not going to be able to eat.
Should i consult a doctor or is this 'just one of those things'? i don't know anything about food intolerances and am not sure whether they are resolvable.

I too developed an intolerance to most fish (and some other foods) after giving birth - I get cramps and have to run to the loo, but it's over fairly quickly. I can eat most white fish and for some reason I'm OK with tinned tuna, but oily fish are otherwise bad, and shellfish impossible. I can eat one bit of soused herring, for which I have cravings every now and then. I've just accepted it, but have noticed that things can change. After having DS2 (now 18) I became intolerant of melon, which really upset me, but discovered about three years ago that I can eat it again. I'm not risking strawberries just yet, though.

You want to put a thread in the allergy section aswell incase anyone can give you advice there.

thanks, i didn't realise there was an allergy section. will hot foot it over there now...
