I underwent bypass on June 6th. Am taking dilzen(3times), ceruvin AF 75150 noon and cordace morning. Being diabetic i take novapad 24 units once and shortacting 8 units thrice. I am taking throxin 100mg also once. though surgery wounds have healed still there is severe burning sensation on surfaceof stomach on the right side. My diabetician says it is not due to diabetis. Why this burning sensation? Are the internal wounds are not healed?
