Patch
Subacromial Injection
Patch will be applied directly to the lateral tip of the affected shoulder, at the site of maximal tenderness. Subjects will apply a single patch at home approximately every 12 hours (e.g., morning and evening patch applications) for 14 days. Subjects will remove each patch after 4 hours. Subjects will have the option of applying the Synera patch as needed for an additional 2 week period (weeks 2-4) if they feel their shoulder impingement pain is severe enough to warrant treatment. Patches will be applied every 12 hours for up to 4 hours as needed during this period.
A single injection will be administered into the subacromial space utilizing triamcinolone acetonide at the baseline visit.
