Have you tried holding your nose and gently blowing, yawning, chewing gum or minties? Go for a drive up and down a big hill? LOL

Hi, l dont know if this will help you, but give it a go......My oldest son always get blocked ears and the GP suggest we put a hot cup over the ear to unblock it...sounds weird but it works on him. Just heat water, add to mug, leave water in mug until cup is hot, empty water and put mug over ear for a few minutes....hope this helps.

Hugs xxoo
