Thanks, Jaylee, for your informative mail. I just watched 'The devil we know' on youtube, on the plaintiffs agains DuPont on the former use of PFOA's and the effects of that on health, especially cancer. PFOA's are forbidden since 2015 in the US and Europe but still produced elsewhere in the world. Where it is forbidden it is replaced by Gen X, which also seems to be a carcinogen.
Ideed, with internet, it is difficult to find really thrustworthy information. There is a lot of fake news, manipulation and emotionally coloured information.
On your question about cosulting a doctor: yes, I have seen various doctors so far and had various tests. They first told me that with diabetes (for 40 years now) and - indeed - hypothyroidism for 27 years now), my joint problems were more prevalent/normal.... But even of these illnesses we still do not know what causes it really.
If teflon/PFOA/C8/GenX are in our drinking water and affects people, what if I place it in my body every day with a canula.
They've sent me home for two years that it is osteoarthritis, but it worsens too quickly and I insisted to take me serious and look at the röntgen and MRI's real good. And now they confirm that these imaging materials really do not give a conclusion of osteoarthritis. Therefore I now have a PET-scan. But, as said, I have no idea what can be seen on those. Parallel I am thus checking with you all. Without wanting to harrass you with worries. But still maybe help you all to stay alert of what we are having prescribed/used for our 'health'.
