Walking is a good form of exercise for a diabetic or anyone else. I would get into see your doctor about the swelling in your feet and legs. There are many reasons they swell and it may not be diabetic.

A good thing to do is to soak your feet in warm water with epsom salts in it for 30minutes as it can help temporarily with peripheral neuropathy. I am very lucky cos in the 29yrs since I was diagnosed with TYPE2 DIABETES I've never had neuropathy. On days when I have to go out ie:shopping, walk my dogs, go out for a meal I always get my foot spa out so I can give my feet a good long soak in warm water with 2 measuring cups of non-scented plain Epsom Salts and when I have to cut my toenails I always soak my feet for 30minutes first then dry them and moisturise with GOLD BOND DIABETIC MOISTURING CREAM/LOTION. afterwards before I put clean diabetic socks on. If you haven't got any GoldBond then E45 cream/lotion helps too. When it's hot in the spring/summer early autumn wear sandals or ventilated summer shoes so your feet can stay aired and try not to wear trainers in hot weather cos they make your feet sweat too much. A good way to deodorise shoes and trainers is to put a teabag in each shoe/boot/trainer overnight it gets rid of any nasty smell from shoes, trainers etc! GOOD LUCK!

ditto Jerick! Also, the swelling might not be from diabetes. It could be from your PAD. I would definitely have it check out, especially if it's been happening for a while.

PAD is when glucose levels are too high it damages veins and it restricts blood flow to limbs and feet.

PVD is ARTHEROSCLEROSIS!
