Are they actually blocked or is the ear canal infected and therefore swollen, making it feel like they are blocked? Only a doc can tell you that. Also, what and how are you cleaning them?. Cotton buds will lead to an infection as tiny little strands come off the bud and attaches to the hair in your ears causing real problems..
See a doctor, it's not yet an emergency so even if your practice can only fit you in in a fortnight, still go.
