rash all over my body

hey im 15, recently i had a rash after going to my fathers house, i took a course of anti histamines when i got home and it went i have recently  gone back to my dads again (slept there for 1 week) and its came back, i took another course of antihistamines but it still hasnt gone , they are using the same stuff as usual ie soap powder , air fresheners help would be appreciated
my arms are the worst effected place my legs have cleared up quite alot, and so has my torso i think it maybe my blazer? that i have to wear for skool it has been at my dads (he smokes) and thts the only thing that covers my arm for the whole week basically
any help would be appreciated
my hands are scaly kind of and my arms look like sun burn not like a typical rash, doesnt feel hot to touch either help !

my arms if they get cold, ie short sleave shirt on outdoors, they go blue where the rash is not really blue but purpally, when i press the red parts on my arms( basically whole of lower arm up to elbow,) it goes white for 1-2-3 seconds

another thing i have noticed on my arms is underneath, i see and feel little hairs poking out, could it be these hairs coming through giving me the rash im not sure, the hairs feel like 1 week after uve had a shave, pointy help please this is getting me worried

Just wondering if you sleep with wool blankets there, as they are rough and if sensitive to it may have some probs? Or maybe sensitive to a type of laundry detergent or softner? Is it itchy?

The blazer may be holding in the heat and making the rash appear worse.  It would be good to have a allergist check into what you might be allergic to. Could be the fabric softner.  Try using ALL free and clear on all your clothes and bed sheets/comfortors. Good luck to you.

i believe when i dont have my blazer on or havnt had it on for long periods it looks better, you cant really notice the rash but i know its there if u get me

[ginjaninja]

no mate, my rash is not itchy, my legs etc were but they have basically cleared up my arms and top of hands are worst affected
many thanks for your reply i also do not sleep with wall brackets and my step mum ( dads house ) she does the washing and everytime i get the washing bak it smells so strong ( erm fragranced ) i dont know if she is diluting the fabric conditioner / softener when she uses ?
thanks again

my rash has cleared up ever so well after not wearing my blazer but i still have a few blotchy parts on my arms should i carry on taking antihistamines as i have stopped for 3 days now thanks

Yep, sounds like you're in the clear. I'd stop taking the anithistamines now, too. Start back up if you notice a worsening of the condition. Take care.
