Skin grafting. Before it's too late.

I have undergone skin grafting on April 11th this year. The skin was peeled from right thigh and applied on left leg near knee joint. Everything was fine until it started bleeding from left leg. I'm concerned because I don't know if it's blood, water or again infection. And I'm predicting it's because of my weight(92kgs). My daily schedule is 7:30am- Corn Flakes, 8:30am-Sleep, 3:30-4:00pm- wake up, 4:15pm- limited rice. 11:30pm-12am- dinner (3 chapatis). If I walk a lot I'm bleeding mostly while I'm at work. A month ago my regular doctor who has performed the surgery has given me some vitamin tablets and a Zero Fat A capsule to reduce weight, but no change yet. I really need some help before it's too late.
