<s>[INST] I started on the 18th with a severe itch on my entire body, including my head. I ate a seafood salad on Thursday the 16th and had a flu shot on the 14th. It is now the 19th and my itch is still with me. I have tried benedryl tablets and calamine lotion. not much help. thank you for your assistance [/INST] Hi i did review your concern.Very rarely some people have hypersensitivity to influenza vaccine and especially if you have egg protein allergy.Mostly it will go down in some time with benadryl and loratidine.I hopw this helps.Wish you all the best.Thank you for choosing healthcaremagic. </s>
