There is much in your post to respond to, I will try to answer some of it, and others can add in more response.
As for the Neproxin? Do you mean Naproxen Sodium?? That is a NSAID class drug, and is not advised for long-term use while taking Blood Thinners (Apixaban), as it can cause the blood to get to thin.
Also, there is not alot of literature on this, but from my experience and research, Naproxen Sodium is not a good choice for those with AFIB risk, as the drug alters the NA+/K+ ratios in the Atria both when you start taking it, and then also when it is discontinued. Alterations or shifts in electrolyte balance can increase risk of AFIB.
The paracetamol (Tylenol) can cause liver values on blood tests to appear worse, but rarely causes serious liver damage.
Perhaps a primary care or pain doctor could be of help here, in selecting the right drug regimen for your complicated situation.
