Severe neuropathy with CF & other questions

I am wondering if anyone with CF has severely effected nerve issues? I do not yet have a dx, I had CF come up when seeing a geneticist and just had my second test ran a few days ago. It is a long complicated story but I have severely effected nerves throughout my body, including my eyes, of course with many other symptoms but I am very curious about this. I have had several abnormal nerve studies & the drs cannot interpret what it exactly could be from and since we are born with the nerves the way they are I was wondering if it could be a cf possibility? Also, does anyone NOT sweat at all? Or have had your menstrual cycle stop for 6 mons or more without finding a cause? & is diarrhea and low grade fevers with chills and being cold and shaky a part of CF? Thankyou for any input with all this....
