I started using Tetralysal 300mg for my acne's. No matter what I did, the scars stayed inside my skin. They are reddish or a bit purple. I always need to wear make up on because they really disturb me. Since two days, my right ear started to hurt, it's not strong at all but i feel like it's blocked and I have a serious problem with the pressure when i'm flying, i always get cramps but i didn't fly anywhere soon or did something to heart my ear, except listening to my Ipod very loud :/ I wanted to know if this can be a side effect of the antibiotics and that I should stop using it or because of something else. Thanks
