The O’s 1-0 defeat in the only National League game to beat the weather wasn't helped in the build up.
Edinburgh was without a number of players at the Crabble but he blamed a lack of focus and not their sickness problems for the loss.
A Mitch Pinnock goal seven minutes from time was their undoing - but the Whites were given a helping hand which frustrated their manager.
“It’s a really disappointing end to the game for us,” he said. “We really should have been coming away from the game with at least a point.
“We were fast out of the blocks and look efficient from the start.
“But an individual error has ultimately cost us the game.
“The weather has been a disruption, but we have also had illness. Chest infections and food poisoning this week really didn’t help our preparations.
“It wasn’t ideal, but we have players out there who could help us cope with that but we haven’t been able to get a result.
“We had a number of good performances and a few very pleasing first starts but unfortunately a lack of concentration has cost us the game.”
Orient’s next fixture is Tuesday’s FA Trophy quarter final replay up at Gateshead.
