The vein below my right thumb over my wrist is swollen. My right wrist feels painful. The pain is exacerbated with movement, use of thumb to do pretty much anything - hold a pencil, turn a knob, lift anything. This pain started two days ago and got worse with use. So, today I started wearing a wrist/thumb brace to remind myself not to use it. It helped. But when I took it off this evening to wash my hands I noticed the swelling of the vein I mentioned, plus a little swelling below and to the right of that area. Also, while the brace was off I pulled on some velcro with my right hand/thumb and now theain has extended to my elbow . Any thoughts? Recommendations?
