Hey Stray,
Sorry to hear bout your news, I'm UK based so you might wanna check up but heres a few points
1> Any work related accidents or injuries
Must be reported in writing usually in a designated book.
As soon as practical and certainly after being diagnosed
2> Check your insurance car/house you may have cover for free legal advice.
3> If you leave a job due to health reason's you "may" have a problem re-applying for other job's unless you can proove that a>your injury has healed b> the injury wont effect your new one.
4> Make sure you keep of all letters/conversations/doctors appointments. Also if you need any therapy, keep recipts as you could claim these back.
5> Are you a union member ? They can help
6> RST - or Repetative Strain Injury, or injuries resulting from or in RST, ie Tenetdanitis Tennis elbow are usually caused by inflammtion. You can take AIA's or Anti-Inflamatory Agents, such as Ibuprofen alongside painkillers.
Aint-inflamatory drugs work better than Pain killers cos your redusing the swelling, also hot compresses applied on and off in 5 minute burs't DONT USE "deep heat" type rub's there chemical and dont really work, direct heat or anit-histimine creams are better.
If you DONT rest your hand, t will only get worse. As your wrist is fairly important and a beech to heal.
However GET proper reputable LEGAL advise.
Oh another point if your work put you to counter work and YOU dont like it and go back to any kinda work which will aggreviate your injury, they can turn around and say it was your fault cos they offered to help you overcome your injury and you ignored it.
Also I "think" if you ignore health issues you are contraveneing any health and safety at work practices.
Stay safe
Adrian
