I just recently started at UPS as well and I have had the same prob. Check with the doc I guess thats what I will be doing. It is from cardboard mites if I'm not mistaken.
Could I Be Allergic To Cardboard?
I've been working in an office for almost a year now and I have to open boxes of inventory all the time. I was fine, up until last month...ever since I've been getting rash outbreaks on my arms as well. Is it really possible for one to suddenly develop an allergy to cardboard and cardboard materials?
Yes, cardboard boxes were delivered to my office today and my asthma kicked in something fierce
