I am 19 and have been using onesource "teens" vitamens for a long time (one bottle and its been dragging on). When I ran out not too long ago I decided to buy some centrum atoz. A week after I started to use it I noticed dry skin on my right hand, mainly around the pinky. Just a few days ago my mother pointed out that I have a red rash under my arm pit (i told her it was a cat scratch so I would not scare her). I looked in the mirror and it looks as if its rubbed skin. I have the same spot on both arm pits. I am a little concerned because this did not happen until I switched vitamins.

P.S. When I switched vitamens I went to the doctor for a wrist problem and took some ibuprofen tablets (only took about 10).
