Could I have gained weight from exercise?

Two weeks ago I started lifting upper and lower body weights and performing cardiovascular exercises four-five times a week. I got on the scale this morning, and it looks like I am up five pounds. I have not changed my eating at all from the previous weeks. Additionally, I have had terrible swelling problems from the knees down three times since surgery. I noticed by legs are red again (they often look sunburned), and when I push on them they stay indented for a long period of time. So, I am sure I am holding water again. I have seen the doctor regarding this, lots of tests, no answers. I don't think they know what causes this. I am disappointed over this, as I was really hoping the exercise would boost my metabolism. Oh yes, I do drink lots of water. Sometimes over 100 ounces a day, generally, about 80 ounces. I don't think I really want to commit to more than this amount. Any ideas?
