AFTER Inside Elbow Test, Severe Itching, Stinging, Swelling [SEP] I put half a patch inside arm at elbow for several hours.  No reaction.<br /><br />Placed under one eye.  Immediate itching, stinging, and after removal, swelling.  Obviously, I am allergic.<br /><br />I only blame the product for not warning of possible reactions. A few reviewers mentioned stinging or burning sensation upon application.  The seller should put in stronger warnings and mention that an inside elbow test may be fine, but under eye skin is much more sensitive.
