My right leg, from my knee down, often swells up and hurts. I walk at least 45 minutes five days a week for about months now. Im obese at 230lbs Im 5 foot 1 and female. I recently joined weight watchers and have lost just over 20 lbs. I thought my leg pain would get better but honestly it s much worse. If I walk too hard or far, if I dance, if I wear heels, my leg is messed up. Do I need to worry or should I just keep walking and losing weight and trust it will get better
