Hi, The base of my thumb on the palm, has been hurting for a couple of weeks now. It started when i took a shot to it from a frisbee but that subsided in a few days. However, the area is still slightly swollen up. Interestingly, my left hand also has a similar swelling to a lesser extent in the same region. I experience very mild pain around the general palm area as well. Thoughts? PS: I have kidney stones and recently had some mild hematuria if that s related in any way,
