You could also try asking the pharmacy for olive oil ear drops, they are very good at softening wax.
You have to fill the ear cavity, lay down and let the oil penetrate, for 5-10 mins, then repeat on the other ear if blocked, use cotton wool to dry up any excess oil which runs out.
The ear may feel more blocked after initial use of olive oil drops, as the wax expands as it softens.
Never poke anything down the ear such as cotton buds or hair clips, and if you have ever had a perforated ear drum, then ask a Dr or practice nurse to take a look, to make sure there is no infection present
Warm the olive oil a little bit before putting it in you ears, much more comfortable.
