...Is dizziness or slight change in vision, as well as a tightness in my jaw in relation to a fish allergy?...I had pollosk fish today, just a small amount and sooner after i felt a little light headed, the lighting was...off (not normal)...its had to explain and soon after one side of my job began to get sharp random pains...and felt a bit swallen, not on the outside at all like deep actually in my jaw. If that makes any sence, I noticed that ive had all these feelings before but only after having fish...even though i never eat much of it, but everytime this happens...im beging to think i may actually have a mild allergy towards fish??.....so my question is, can fish cause those symptoms....

### output:

Hello. Thank you for asking at Chat Doctor. I went through your history and would like to make following suggestions to you:1. In reply to your main query, Yes, it is possible that you could be allergic to fish. Personally, I would suggest you to go for skin testing or serum specific IGE to fish to confirm/support your allergy.2. If both of the reports are negative, it is very much possible that you may have histamine fish poisoning. It caused by consumption of improperly preserved (improper refrigeration) fish. The symptoms are more or less similar to allergy, but it is not an actual allergy, it is a kind of food poisoning. So, if your testing is negative for fish allergy, you could take a chance by eating fish from a reliable source. For fish allergy, the best strategy is to avoid it. Hope above information will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards.
