"took this for undiagnosed joint and abdominal pain. it helped a little, but even on the 20mcg, i still have a lot of breakthrough pain. then i put a patch on two days ago. woke up today with a horrible burning at the patch location. it was so bad, i had to remove it. the skin underneath was bright red and &quot;burnt&quot; looking. it was red both under the adhesive area and under the part where the medication is released. not sure if i can keep using."
