I posted here before ( Laura from Michigan) about carpal tunnel and I had surgery 9 years ago. No I did not have any restrictions. Like I said in my previous post that I had worked at another job prior to my carpal tunnel as cashier and did some lifting with no problem for a year before I started this job.
I was cashiers/clerk (at my previous job) and I was squeezing a scan gun for 3 years and 3 months, 32-40 hours a week 5-6 days and lifting 2 days a week.
I started to have problems 3 months ago. The person who decides (from the company I worked for) if I shall get workmen comp denied me because she said that it was a pre-existed injury which they do not pay for.

Be sure to appeal the denial. If you need any assistance in understanding the appeal process let me know. Good luck. I think that you should be eligible.
