It's cetainly more likely to have been an abcess with a quick recovery like that. Once an abcess starts to drain and the pressure is relieved a horse can go from three legged lame to hardly a limp almost immediately.
As far as the Hooflex, I wouldn't count on that being the problem, but continually having wet feet or something applied which traps bacteria does make abcesses more common, even in healthy feet. Especially this time of year with the rain/snow and unavoidable mud it creates, keeping feet dry is usually beyond our control. The best you can do is pick them out and old timers (including me) will apply iodine/betadine after to help kill any bacteria and dry the soles.
