How long should I expect to wait for a decision to come back regarding Medical query? I'm expecting answers along the lines of 'how long is a piece of string' but was looking for indicators of what I should expect. In the past how long has it taken for other people to receive a decision back from their medical investigation!? I had my medical on 8th April 2009 and still waiting, I have been pestering my CO on regular intervals with no further info coming back. Any help or indicators would be very much appreciated!
