I Have The Feeling Of Itchey Fiber Glass On My

I have the feeling of itchey fiber glass on my hands and arms. I haven't been working in it though. this has been going on for about a week. have used lotion to some degree of help . I thought maybe it was my diabetic meds Glipizide and didn't take it for a day. symtoms seem to leave but returned a day later. I've taken benadryl and it seems to relieve it some.
