Oh man, I have gotten calf cramps for YEARS. I've been dealing with that sh*t for more than two decades. It's never enough to go on medication or see a doctor, but like once a month I'll just get a sudden, sharp and painful cramp in my calf as I'm sleeping, and I have to jump up out of bed and walk around the room to work it out. It is easily the most painful thing I have ever experienced in my life.Obviously, since I've been dealing with that for 25 years, it has nothing to do with my BFS. Angst is right. Simultaneous symtoms don't necessarily mean correlational symptoms. Stuff can overlap.
