question about muscle spasms
I have a question for anyone experiencing "muscle spasms?" What is meant exactly by this term?
Sometimes I get an almost excruciating pain deep in my thigh. It lasts for a few seconds and then passes. I get that several times a day. Also, if I barely overstretch certain muscles in my side, foot, back it tenses up for a minute or so and then lets up. I do NOT stretch and am not very limber.
I'm wondering if either of these is a muscle spasm or is a muscle spasm something far more severe? Does it hurt a lot? How long, in general, does one last?
Thanks for any info.
