HI, I AM A 7 YR. OLD OBESE FEMALE W/LOW

HI, I AM A 7 YR. OLD OBESE FEMALE W/LOW ACTIVITY LEVEL. i AM DIABETIC, I HAVE HIGH BLOOD PRESSURE, FIBROMYALGIA, ARTHERITIS. WHEN I'M ON MY FEET FOR AWHILE , SAY SHOPPINGG, WHEN I GO TO GET IN MY CAR I LITTERALLY HAVE TO LIFT MY LEG TO PUT IN THE CAR. THIS TIME IT FELT LIKE IT WEIGHED 1.000 LBS. I HAD TO USE BOTH HANDS TO LIFT IT AND STILL ALMOST DIDN'T GET IT IN NOT TO MENTION LOSING MY BALANCE. ANYWAY THAT WAS 2 DAYS AGO, IT IS USUALLY BETTER AFTER A REST IT ACHES I GUESS U WOULD CALL IT ALL THE WAY TO MY GROAN, DOES THIS SOUND LIKE A BLOOD CLOT?

THANK YOU
