I have just been given details of my medical pension. I have been awarded a lump sum of £18,000 and a monthly payment of £500 a month. It's more than I was expecting tbh but I would still rather be in the RAF, going to miss it.
You will miss it mate, for a start you're going to have to work for a living now

I left in Nov 2008 on a Medical Discharge (MD) after 21 years service and I still miss the Army. However, I'm now working for the MoD as a Civil Servant doing the job I got released from! The pension is a godsend and pays for my mortgage which takes a lot of stress away. PM me if you have any questions as I have quite a lot of info about what you may be entitled to etc.
