very worried

i had unprotected sex over a year ago with a guy. a few weeks later i started to have flu like symptoms, however flu season was in full effect all over and at work, so i figured i just got it from there. i was later involved in a car accident where i was in the hospital for 4 days having surgery while i was in the hospital. i have had 2 more surgeries since. anyway about a month ago i got a swollen gland in my left arm pit that was pretty sore then in about a week went away, now i have noticed a reddish bump on my left breast that is maybe 2 cc in diameter no more than that, does not hurt or itch. when i look it up on the computer KS comes up and is mostly associated with hiv.. now i am freaking out. is this a sign/

Symptoms are not an effective way to identify HIV as up to 40% of people who have been infected get no symptoms at all, the only way to be sure is to take a test, test at 3 months post exposure for a conclusive result.

would blood tests show anything from when i was in the hospital?

As Mitch rightly said, symptoms do not mean much when it comes to HIV, because first, they resemble with those due to other illnesses second, many actually infected people remain totally asymptomatic.

You may get yourself test right away to know your conclusive status, bury all your worries to rest permanently and move on. Wishing you a very good luck

No ! Only specific antibody test determines the HIV status. And this test is ordered by the doctor if he is aware of such kind of exposure, other than  routine initial pregnancy tests and blood screening for transfusion (this test is not an antibody test but a different one called NAT)
