I've had a bit of a problem with my ears the past week or so - They feel a bit blocked up, and I have the loudest cracking noises when I swallow.I went to the doctors and she said she couldn't see anything wrong but that it might be fluid behind the eardrum (kids get this when they are young, and then they have gromits put in so the fluid can drain out. She even asked if I had them when I was younger, which I haven't) So I have tablets to take for 3 weeks for that and then the Tetralysal is for spots, which i've been getting. I have to take them for 3 months! So many tablets..
