Hi there
I suggest you use pain as a guide and damped down the activities that you suggest are aggravating it. There is a small bone in the wrist (scaphoid) which fractures sometimes when ppl fall on outstretched arms) this rarely shows up on x-ray and sometimes gets a bit better after a few weeks then worse again (seems to follow that pattern). On the other hand if it is tendons then putting your entire body weight through them may not help much either, You'll need instead to stretch them eccentrically over a long period of time, don't start with the dumbells introduce them gradually.
What movement is the most painful? Have you noticed after all this time anything that eases your pain?
