I’ve been on a medication in and off for 4 years I started taking it again 3 days ago at night the first morning after I saw 3 red circles on my arm didn’t think much of it every day I’ve been itching non stop and taking antihistamines which are not helping today I am covered in hives legs stomach bum 
and arms they’re definitely hives as my son had multiple allergy’s the only thing that’s making me think it’s not the meds is I’ve been eating apricots for about 10 days and haven’t eaten apricots in years of cause it’s friday and my pharmacey and doctor are closed so what would you advise if it’s relevant I had a reaction to a different medication about a year ago in similar circumstances stopped taking it for a few months and started taking it again but that time my throat swelled so we where quite sure. I’ve never had any allergies before
