Did you ever find an answer? I just woke up with this exact same thing. Right hand, ring finger, sore between my joint closest to Palm. Really feels like I've jammed my finger but all I did was sleep.
I'm having the same, I'm thinking I have Gout...I'm taking a cherry extract and am going to drink lots more water.. I don't want to tak nsaid's I'm trying to use Ice as much as possible.. good luck,
Every joint in all my fingers on my left hand are extremely sore. My hand is swollen but not so bad I cant make a fist, Pregnisone is the only thing that gives me partial relief but I cant continue taking this. I had trouble with this problem a few years ago then it stopped. I had 5 different Rheumatologists look at it and all had a different synopsis. My hand feels like I hit a concrete wall as a hard as I could. Any suggestions?
It is possible you did something slight, not realizing it, that caused a minor injury to the area. Maybe even jammed it in your sleep. If it doesn't go away after about a week (ish) it might not be a bad idea to consult with your doctor if for no other reason then to rule out arthritis. Do you have morning stiffness lasts less than 1 hour then returns at the end of the day or after periods of activity? Or is it sore and swollen all day, reguardless of activity?
