Howcan i treatlowerbackpain:o i'm a soccer player and haveonly two days to rest it ?

Depends on the pain: It depends on how severe the pain is and it's duration. If it is just an ache and short lived and does not stop you, it is ok. Otherwise, try cross training if only doing one type of aerobic exercise and incorporate stretchiing and core muscular workouts as well. You can try otc medication if no medical reasons that would prevent their use. If it persists, then seek evaluation if bothersome
