Hi ouch,
Congratulations on your excellent award and thank you for sharing the news with us.
It really is up to you whether you ask for the evidence they used. But if you didn't have a medical then they are only likely to have contacted your GP or other health professional you see regularly.
Some people are reluctant to ask for copies of evidence after a successful award for fear that it might cause a DM to look at the decision again. Whilst this shouldn't happen, it does seem to occur occassionaly.
Good luck,
Steve
