leg cramps

I don't mean Charlie horses either. My leg feels like it's having a growing pain and it's horrible! I'm 24 I'm not growing anymore lol is this common in pregnancy? I'm 32 weeks. Maybe I slept on one side too long when I took a nap? Idk, all I know is this is so painful, I was limping down the hallway. I've rubbed medicated muscle stuff on it twice, which only relieved it for about 10 minutes. Ugh.
