Thanks for providing more information.
Firstly your BMI(body mass index-measure of body fat based on height and weight) is fine.
Now swelling in lower legs can be caused due to fluid retention resulted from possible causes like Venous insufficiency,Lymphatic obstruction.
Swollen calves & feet may be a sign of heart failure, kidney failure, or liver failure.
Numbness and tingling sensation in legs can be caused due to Lumbar radiculopathy(compression of nerves at Lumbosacral spine).
So you shouldn't ignore your symptoms and it's good to consult your doctor ASAP.
Elevate your legs.
Exercise your legs
Follow a low-salt diet, which may reduce fluid retention and swelling.
Avoid alcohol and caffeine.
IgA Nephropathy can also result in swelling in lower legs.
So further Renal function test ,Complete Blood Count,ESR,Blood pressure monitoring,Color doppler study of lower limbs,EKG should be advised for further evaluation and management.
