Oozing/Bleeding through steri strips?
My first thought is that you have been over-doing it. If you do too much you can cause some of the sutures to tear, and bleeding to occur. If it's just a small amount of bright red blood with no foul odor, I'd just clean it up and see if it stops. If there's any redness, odor, or swelling, or if it's more than just a little blood, I'de call asap.
Wow...you are the first person I've read about that has had this problem. I was told not to lift anything for at least 10 days to two weeks and to not do any strenuous exercise right after surgery. I recommend you call your doctor in the morning to see if you need to get checked. You don't want to risk an infection.
