yesterday i noticed a itchy/burning on my upper arm and noticed a huge rash. in the next hour it slowly crept up my neck and face and i had little red dots all over my body. i took 2 benadryl because i thought it was an allergic reaction. the next morning, the rash spread to my cheeks and i had developed new ones on my body. some of the smaller red spots had grown into a bigger blotchy rash. they are no lower rashes below my hip bone. i went to the ER this morning, and will be going to the doctor tomorrow morning. they gave me: fenezal 25 mg, loratadine 10 mg, and panafcortelone 25 mg tablets to take. they don't seem to be working, except for right when i take the fenezal the rash on my arm got lighter, but not the blotches on my body.
i don't have allergies, and i had not worn, eaten, or done anything i haven't done before. the doctor thought i could have developed an allergy to doxycycline. i've been taking doxy since december for acne, 100 mg a day for the first 4 months and now 50 mg a day in the morning since then. i had taken doxy that morning though, and got the rash over 10 hours later. i researched it, and doxy has a bad reaction with the sun but i have always gone into the sun with doxy, and i used to get a nasty sunburn but that was it. plus my torso hasn't seen the sun for weeks.
please let me know what you think it is! the doctor thought it would take 2-3 days to clear, but i thought if it was an allergic reaction it should clear as soon as i take the antihistamine?
