Possible exposure after 24hrs?

[G027]

About 20 days ago I had a hookup with a guy, used a condom. The next day during the afternoon I noticed burning near my waist and noticed that I had hives or welts around my belt line. I'm not allergic to anything like that. It was pretty severe. I developed a sharp burning pain on my upper back too and found hives on random parts of my body. It went away after a week. a week passed and I have random red dots appear on my arm. And they'd go away within the hour. At other times I get a small hive and it doesn't itch, it just appears and it'll go away. No other symptoms besides headaches and dry eye/mouth although I think maybe that's just stress. I've heard that ARS symptoms don't appear until 2-3 weeks, and I can't think of any other STD, if it is that, that could cause these symptoms. Any clarification could help.

HIV can be transmitted via UNPROTECTED vaginal or/and anal penetration, sharing IV works in drugs and from mother to child

I'm just concerned because these symptoms appeared immediately after I had sex, so I'm not sure if skin to skin caused something considering I still get red itchy dots that come and go on my arms. I have no other symptoms.
