I Am 72 YEAR OLD THAT HAS HAD MANY HELATH

I am 72 YEAR OLD THAT HAS HAD MANY HELATH PROBLEMS most RESULTING IN SURGERY. I HAVE JOINT PROBLEMS THAT I BELIEVE RESULT FROM AN OLD OSTEO MYLITIES GRAFT IN MY RIGHT FEMER WHEN I WAS YOUNG. my CURRENT COMPALINT IS THAT MY RECENT TRIP TO NORTHERN EUROPE HAS LEFT ME WITHOUT ANY ENERGY. I CANT GET AROUND WITHOUT FATIGUE AND SOULD SLEEP ALL DAY. I CAN WALK THROUGH THE HOUSE AND HAVE TO SET DOWN FOR AN HOUR. ANY NORMAL DUTY LEAVES ME WITHOUT ENERGY. I WILL BREAK OUT IN A SWEAT ANY ANY ACTIVITY. recently I HAD A STRANGE HIGH PITCHED SOUND IN MY LEFT YEAR THAT LASTED FOR A LONG TIME AND MY LEFT ARM SEEMED TO BECOME ASLEEP AND NUMB. cOULD THIS HAVE BEEN A STROKE?
