Need to be very careful with wrist injury. If you overstrain your forearm, usually the pain is on the forearm muscle and tendon near the elbow, but usually it will recover within a week or so. But if injured wrist, better stop all heavy lifting, it may (or may not) recover at all.

But if accidentally sprain your wrist due to fall, better go consult doctor fast. I remember when I was small, I accidentally sprain my wrist due to fall, and it swell up (you know la, still small that time). Take me about 3-4 weeks to fully recover. First week can't even hold anything, the swell start to subside on the 3rd week. That time didn't see doctor, but luckily it's ok now.
