Cyclobenzaprine - Has anyone gotten severe leg cramps after taking 10 mg of this med?

I took a Flexeril last night to hopefully relieve the pain in my leg from cramp in left calf that occurred 2 nights ago after taking 3mg Valium. I’m not on any other meds but took Valium 2 times for pelvic floor dysfunction and got the worst cramp in my calf I’ve ever had! Tried a Flexeril instead last night and now cramp in other leg. Sends me to the floors reaming in pain in the middle of the night. Now I have 2 very sore calves. Maybe they over relax the muscles then they cramp up later as med wears off? Worse then childbirth pain.

I have been on the medication for 6 weeks. I have had severe leg cramps for 5 weeks. Had no idea it was the meds. Nothing else in my routine has changed. It’s so bad, I have woken my husband up 5 nights in a row trying to get out of bed. Walking helps, but it can still take 30 minutes to get rid of the cramps. It always starts in the calf. I’ve had them move down to my toes and around my ankle. Good to know I’m not crazy. Done with this medication now.

I took .5 mg of Flexeril for the last 10 years and it just now started causing me cramps at night I took one in the morning one at night I quit taking the one at night in my legs quick cramping but I need to find something new I was taking flexor all because of my bad neck and now my neck is starting to bother me due to the fact I don’t take it at night now so now I don’t know what to do is there another muscle relaxer that could replace the Flexeril

Yes I have. I mean some wake you up at night screaming leg cramps. Bout 3 to 4 hours after taking also. But dummy me, took more thinking the first dose wore off. Then I really was in pain!!

I just had the exact experience.Bad experience with calf cramps... after taking same medication... I thought it was very strange..thank you for this question I know this is not a answer but
you helped me .

I am no doctor, but I can tell you from lots of experience, every single time I take Flexeril, I get terrible leg cramps. I don't know why but I experience this like you do.

Does this med cause shakes. I was taken off it for this reason

That is a very peculiar side effect from a muscle relaxer. I'm sorry you had to go thru that. Obviously its not the one for you.
