You are probably over compensating one side when lifting. For chest, I would concentrate on some dumbbell bench pressing and try using a little heavier weight on the smaller side. Also concentrate on form, don't hurry the lift and be in control. Always try to be even on your lifts, don't cheat with the strong side.
