Hi dear lady. Welcome to HCM, question service.
After reading your actual situation, and taking in count your age and given information, this is the analysis:
If there are not comorbilities, like cardiovascular, renal, or hepatic troubles,
diabetes or
hypertension, you should evaluate your leg and veins actual situation.
Do you notice your veins (in legs) more than before?
Are you feeling pain, and heavy at the same time?
Do you have family background
varicose veins trouble?
If this answers are positives, probably you have varicose vein trouble, which causes, pain, heavy legs sensations and other complications as ulcers. The causes are variable, but the principal problem is an insufficiency of veins valves, which makes backflow of blood, and accumulation in the lower
limbs.
Be careful, and here I am to answer other questions.
My best wishes to you.
