question: I have a cyst-like structure on the volar aspect of the wrist. Before, I thought it was just a bone but ~1wk ago, it became tender and was painful upon any pressure. Awhile ago, i felt the pain like it was pulsating after bending my wrist. I palpated the cyst-like structure & it was similar to a radial pulse. I first felt the pain last July 2011 but it was on and off. I think I have TFCC tear on the area too. What could the cyst-like structure be?
