Lidocaine
"I was prescribed these patches for pain in my knee due to chondomalacia and a dislocated knee cap. They really don't stick to my skin (even after washing the area and drying well) Also they're hard to put on the knee cap where my pain is, they just ball up and fall off after 30mins. I've found cutting the patch in half and surrounding the knee works. It helps with pain but nowhere close to being a 10/10 in my book let alone a 6/10."
