Am I allergic to latex condoms? HIVES ADVICE PLS

💙💙💙
Last night I slept with someone for the first time in a while and of course we used a condom.Everything is fine but I have broken out in hives, starting front below my armpits and spread down my arms to my wrists and my legs to my feet, but not near my vagina. I have used a condom in the past but did not get this reaction. Could I have possible developed an allergy? And pls comment tips to stop the itching and how long do you think they will last?? Thanksddd
