Suggest Treatment For Allergic Itching On Skin

hiya, we have changed the uniform at work in january and in february i started to experience itchiness on my hands. then i march i has a reaction on my neck where i was wearing the red uniform scarf. it was very ichy and when i took it of my skin was red and felt bumpy and after a few days it looked like my skin was peeling of. i went to boots and the pharmacist gave me eurax cream.i was using it 2 a day and the rash dissapeared but as i wasnt alloved to wear the shirt and skirt uniform w/out the scarf i started to wear the dark navy dress. And it all started again.but now my rash has spread not only to my neck but also to my arms,hands,legs.the worst thing was that it was very red,my skin felt like as if i had a sunburn,very painful and my skin is red and kind of bumpy like hippo skin,very rough and itchy.the warm water and sun aggrivates it and it is very uncomfortable to the touch. i have taken pyriton as well as antihystamines but nothing seems to help. the uniform is made of polyester and viscose but i have never had any previous problems wearing clothes from those materials. i have the feeling that it might be the dye.what shall i do?
