I’ve had 2 injections in my neck. I believe the injections were around c5. I have several bad discs and pinched nerves resulting in constant pain in my neck/shoulders and shooting pain in my arm. The first injection didn’t take but the second one did. For the first several hours, I was fine because the anesthesia was still working. By that evening the anesthesia wore off and my neck was very stiff and sore. It helps to nap a lot. It took a couple days for the stiff and sore feeling to wear off. Plan for the injection on a Friday so you can recover over the weekend.
I had the injections over a year ago and the shooting pain down my arm has not returned yet. They didn’t cure the neck/shoulder pain but did dull it quite a bit. I decided to try injections because I’m not ready for surgery yet.
