feels strange when I make a fist, a bit stiff like i can't close it all the way, but i can. I only had this two-three days so hopefully it goes away soon. Started in my index finger then today a little bit in my thumb. I notice it a lot when I write with a pen. I have tested myself (which i usually don't do anymore) and no obvious loss of strength. I can resist in all directions about the same. I tried lifting a bag flexing/extending my finger and adding weight until I maxed out and it was the same max weight on the other side. I also play guitar and although it feels really weird no loss of coordination, speed, strength. I think (hope) it is just a painless cramp/spasm of those muscles...seems to fit with bcfs. I wouldn't worry too much...people get all kinds of weird but similar symptoms. Remember BCFS is a real disease with real underlying pathophysiology...it is just poorly understood. So it should be reassuring that we are all experiencing these things even though there is no clear explanation. It is a disease that produce odd but a similar clinical picture. Like I said...these symptoms are the theme of this forum.... and rare other sites. BCFS must also be common.... we are both complaining of the exact same symptom within a few days of each other?! What are the chances of that? And it happens all the time here. Anyway, hope you all feel better. Stop worrying...we are far more likely getting killed on our way to work and we dont let the anxiety of that possibility incapacitate us?!
