It's unlikely a regular doctor would be of a whole lot of help, an orthopedic surgeon would be more useful. The only way to diagnose this is probably to get some tests done, but let's say you did hurt this doing that tilling. The thing to do was to do the RICE program, which is rest, ice, and elevate. It's not always the best thing to put compression on something that is injured, that's usually for chronic ailments that can't be fixed so you have to live with them, but with a new injury, rest, ice, elevate. But too much rest for too long can also be a problem. I believe you can see a doctor by video conference if for some reason your local docs aren't seeing anyone in person.
Where does it hurt? Back of wrist (dorsal) or front (volar) and specifically where (in line with thumb, middle or pinky, etc). Worst with extension or flexion? It is likely tendonitis (flexor carpi radialis tendonitis) and agree with RICE but add NSAIDs if able to take them to decrease inflammation.
