Bumps in yard

Last summer I sprayed the yard with an insecticide thinking the brownish color of the lawn was due to bugs. It seemed to help but then this fall the brownish area came back and I sprayed again this time using the same insecticide but liquid. The lawn is Kentucky Blue Grass, in Nebraska. Of course it is frozen now but to walk on it there is bumps all over it making it very rough. What do you think is wrong and how can it correct it this spring? Thanks, NEFARMER
