Sorry Greg, there is such a thing as too much information eh?
Until the day I asked him to poke out his tongue I was completely in real denial that anything was seriously wrong with him, despite him having at least 10 months of progressing symptoms, and we still at that point had no diagnosis. At this point we were still being sent around between dentists, ENT's and facio-maxillary surgeons and having teeth pulled and bits of bone removed from his jaw, various antibiotic treatments and saliva treatments, MRI's, 3D scans, ultrasounds and CT's.
I knew in my heart that moment that something was seriously wrong, even though denial kept me afloat for another 2 months until we had those dreaded words pronounced to us ...
