"have had chronic left shoulder pain for the past 4 years. tried massage therapy, chiropractor, physical therapy, etc., etc. been taking 4 doses of tylenol and motrin for 4 years. finally got my doctor to give me something to help. i have been on the 5mcg patch for 4 days and have been absolutely pain free since. the only side effect has been it itches sometimes at the application site. i can deal with the itching since i am absolutely pain free after struggling for the past 4 years.
