i bought a new sunscreen i hadnt used before it was the dollar general spray kind and i used it on all five of my kids including myself, later that evening the 2 girls complained about stomach aches, the next day both had a rash on chest along with one having rash on neck and ears and the other having a swollen face. i was just wondering if the sunscreen did this considering its the only new thing they have been exposed to, and also the one with the swollen face had gone and gotten a steroid for the inflamation and after 24 hours shes still swollen so how long should the swelling last?
