muscle spasm
"Flexeril is a good muscle spasm medication for acute issues. For chronic pain it is basically not effective. I was hospitalized years ago with a ruptured disc and was given Flexeril 3 times a day. I was so out of it that I could hardly stay awake and it took about a week to get back to normal after I was released. However now that I have had spinal fusion at C4-5 the Flexeril is not really effective relaxing my very hard muscle spasms. I have had 3 surgeries, 2 of them failed. The second was anterior (back of the neck) and cut through the nerves and muscles in my neck. The result is chronic muscle spasms in my neck and generally my left shoulder area. I rated a 5 based on the different indications."
