Hi Fanzio,You need to get a hold of your surgeonI had my 1st surgery and was doing fine and then about two weeks later started coughing up streaks of blood. He took xray and found out I had a stump leak where he performed the surgery. Next day he had to open me back up and fix the problem. He said it doesnt happen often but once in awhile they have to redo the surgery.I know this isnt what you want to hear and it may not even be the problem but you need to get it checked out.Im glad he caught it at an early stage. Mike
