question: Hi I am 36 years female and yesterday after I ate a big plate of spagetti sith sea food I had a lot of palpitations and in the middle of my nEck it shows the palpitation movement up an down. This morning it s not like yesterday but still I can see my neck going up and down. Do you this is something like I am bit exited or it s an allergy of seafood. I love seafood and it happen to me only once. Sorry for My English as I am Maltese.
