Good luck with all of it! Cold therapy may be worth trying - most neuropathy gets better after treatment but if I had my time again I would try it! I also got AF - which put me in a bit of a spin for a while. A Heart Condition! Seven years on, it’s made remarkably little difference in my life and is easily managed, so take heart (no pun intended!). A cardioversion is pretty straightforward and there are also other treatments. I have been on beta blockers and blood thinners now for several years - a couple of pills a day and I live normally. Best wishes.
