Wrist hurts?

Hey,

My wrist has been hurting for a few weeks (5-6). However, until yesterday it only happened with certain movements and it didn't really bother me. Since today, however, it has gotten worse. I can still move it "normally," but it hurts. It hurts especially when doing things like putting on socks, waving, etc. Does anyone know what this could be? I find it a bit strange that it's been going on for a few weeks now and I have no idea what's causing it. I'm also in the fire service, and at the weekend we had a performance test where we had to connect hoses, throw them, etc. I've been able to do these exercises completely normally for the past few weeks.

Best regards
