pain
"Put patch on for night time relief. Woke next morning with blisters and welts in the area. I now know the extent of the medication - the blisters and red marks - like a second degree burn spread throughout an area 2 - 3 times the size of the patch. Sitting, leaning back has been difficult. Wearing clothing has been difficult. Laying in bed has been painful. The Doc has given me an ointment for my skin and meds for the pain. The blisters have drained today. The burnt skin is still there. This was the FIRST time I used this product."
