Hello,the bleeding you mentioned is generally trivial, not to worry about. But at times there might be some coagulation disorders which needs medical intervention.Hope you are using things like Ace bandage or Jobst stocking.We know grafted skin does not contain sweat or oil glands, and hence should be lubricated daily for two to three months with mineral oil or another bland oil to prevent drying and cracking.I can suggest you to use Bupivacaine moistened dressings on the site,which will provide some pain relief.
