I have had wrist problems for years. Mainly due to many years of kick boxing and powerlifting. Depending on what type of injury it is, there isn't much you can do about it except warm up well and use wrist wraps. I had a nagging pain in my right wrist for about 5 years and nothing seemed to help it. Even on deca i had some mild pain and you don't really want to mask the injury because you will probably make it worse.
The only thing that helped my wrist was several weeks off from the gym and i quit hitting a punching bag for about 4 months. I know that taking time off from the gym sucks, but sometimes your body really needs a break. When i had knee surgery 5 years ago i took 6 weeks off from the gym completely and since that long break i have not had the same wrist pain i had before. Every now and then i will have some soreness after a workout but most of the time i am pain free.
The pain in my wrist before all of this was enough that i couldn't do dips and some other tricep exercises caused a lot of pain. I remember having serious pain in my wrist for so long that i figured it was just something i was going to deal with the rest of my life, but thankfully it went away after a long break from the gym and hasn't been a problem ever since.
