Liz. Invisalign Day 23. Aligners still out and hoping the coughing, nausea and red throat will all calm down. I awoke in the night a few times coughing, and so had a broken night’s sleep and awoke tired. Today I coughed and spluttered through the day wondering is this is allergy or some sort of infection.  It is quite exhausting. The nausea just came on occasionally but it manageable. No cold symptoms at all so not something I have experienced before as normally any cough follows a heavy head cold. I did have a look online at lingual braces, and there is something now called the WIN system, but it looks horribly expensive, something to think about anyway if I have to have a complete change in approach. No news from my Dentist as he has not heard anything from the manufacturers which is rather disappointing….pause to cough………so hopefully some news tomorrow. I need to get back to normal health first however so whatever they offer everything has to be on pause for now. My dentist did say that is could be a sensitivity rather than an allergy which is is the case he said I would need to try very slow re introduction and see what I can tolerate.
