Hi, Can u help? Please! Yesterday afternoon, I was drinking Pepsi, And I've always been never occuring to itching problems with it, and all the sudden I start itching like crazy! I hadn't eaten or drinking anything allergic to me. So I took this medicane I forgot what it was called and I rubbed it everywhere after I took a shower. Later that night I was fine until I woke up this morning. I'm now countiueing itching like mad. Everywhere! So you know what could've caused it?
