My 87 y/o mother fell and broke her shoulder two weeks ago. While she has nerve pain in her arms and hands previously, because of the way she is favoring her broken shoulder she is having a lot of nerve pain in her neck. We have lidocaine patches that we are putting under the strap. It's on the left near her carotid artery. She is concerned that it could become a problem. Right now it is ~2 inches away. Do you see that as a problem? My mother was a nurse for 50 years and she definitely goes by the book. Many Thanks. Her daughter Rebecca.
