My husband and I are experiencing a reaction to eating a tunafish patty. Symptoms include feeling heavy & weak, weird sensation of stiffness or soreness in neck & shoulders, mild dizzyness, sense of slight blurriness or blotchy vision. In the beginning we felt warm & a little sweaty, but now a little chilled. My reaction is worse than my husband s. It feels hard to type this. Should we get an antihstamine? Or go to the ER?
