I am a 26 year old that is having problems with my thumb. I have had trouble with it for about 4 months, I am having trouble flexing it especially in the mornings. I wake up and its really sore and stiff and it takes about 30 mins to finally where I am able to flex it. Someone had said that it might be out of joint but I have pulled on it and popped it and it is still the same. At the base of my thumb near the palm I feel a big knot or bone. It is not where I can't live with it, it just is really annoying and ideas or anything I would love to hear them. :-)
