Sorry i forgot to mention that the fall was not at work - i was at a relatives house and just missed a corner step after closing a baby gate!. I had no problems before this happened.

The thumb symptoms happened approx 6 months after the fall and the shoulder/arm/hand symptoms developed shortly after this....

The dr's dont seem to be able to decide if this fall caused tos or not.

I think that it will perhaps not be possible for me to claim as it is difficult to prove what caused tos in my case. My job was a heavy phone/typing role and i would take upto 80 calls a day and have to type up notes for each of these calls. I was very stressed and developed heart palpatations because of it - i then changed to a different role within the same company, which was less heavy on the phone calls but involved more detailed typing and reading of files (looking downwards a lot). This role change happened about 6 months before the symptoms started.

not sure if this makes any difference....

Thanks so much for your advice!
