I still use aspirin for fever, body aches, joint pain, headache.  I’ve tried Tylenol and find it doesn’t work as well as aspirin.  Ibupfofen also works well. I’ve never tried naproxen sodium.  Some people take Tylenol because the other OTC pain relievers are said to irritate many people’s stomachs.  If I use these drugs, I have to be careful to read the inactive ingredients. I’ve been known to break out in hives and get wheezy from a petroleum based additive called polypropylene glycol, sometimes written, PEG.  I’m more apt to the kind billed as hypoallergenic, no dyes, flavorings added.
I don’t recommend using OTC meds as a regular thing unless under an expert’s advice. In the past, I’ve gone to an osteopath who recommends plain aspirin except if you have digestive problems or are under age 12.  I’d try a naturopath, but they are not recognized in my state and therefore, you must pay out of pocket.  Mine are pretty much empty!  The only doctor I’ve been to of late is an ophthalmologist due to an eye injury.  I have to return in November for a check up.  He said to use Tylenol if it was painful, but I used aspirin.
