I got muscle pains but not charley-horse cramps in lower legs after 2 years of fighting PMR. Then added more muscle cramps as the PMR declined. History---One 2021 heart ablation knocked out double-heartbeat at age 82, as did a younger softball buddy-- ditto. PMR may be hiding somewhere now but I got healthy enough last year to start sudden muscle pain and weakness again, (Sarcopenia) is now knocked back with daily Creatine suppliment. Slight neuropathy- is shared with many of my young geezer (65 to 80) softball players, who usually quit playing about 76, not recognizing Sarcopenia as poor processing of ingested protein food. Look it up! Creatine allowing 20 minutes/day hard bike ride, plus yields me little calf cramping, serious pickleball AND softball games at age 84.
