ve been dealing with major back and neck pain for the last week. Yesterday around 11a, I took a 5mg
Flexeril and boy did it do wonders. After a brief nap, most of my pain greatly subsided. The following hours, about 10p, I did see an uptick in stiffness but nothing compared to the pain before the Flexeril.
I know Flexeril has an unusually long half-life, about 18 hrs.
