It is related directly to excess fluid and, to a lesser extent, immobilization. You know our song, "RICE"! It does happen to most of us, and most of our fixations are still intact. I know, it's easier said than done, but here goes anyway, "Try not to worry." If your pain level (except the moment its happening) isn't any higher than it was previous, its ok. If its higher, or you're really in a panic and NEED to know, call the office and ask for an xray. More likely than not, they'll talk you out of it, and tell you it's "normal". But, yes, we all understand you're a repeat, and that would make any of us more determined that nothing go wrong! I'm a first timer, and I freak out almost daily! You're in many thoughts and prayers, and your toe will not move!!!
Sophie, I'll look forward to reading what your Doc says. Mine said, "No, It's not normal, and its not ok. But it happens, you have excess fluid built up, and your muscles are trying to force it out. You'll have to live with it." Even now, with most of my swelling gone, I awaken in the night and early am, sometimes a quick twitch, and sometimes an extended flex that won't release for several moments.
