Thanks to all the advice I've received on here. I had my appointment at the clinic. The doc doesn't think it is too likely it is cf causing my problems now but because of by previous high sweat test levels and childhood diagnosis he wants to retest everything. I am having a ct scan of my sinuses and chest, sweat test and gene testing and will go from there. I may never know what I have/had but at least I will be able to finally conclusively rule cf out ( hopefully) thank you all for the support and ideas.
