Phisical therapy Day 2

So I went to Physical Therapy yesterday. They put more heat and electricity on it. Then they massage it and did something else to it. Then they had me do some knee exercises. They also put me on the bike for about 11 minutes. Then they had me do some other sort of exercises for about 15 minutes. They then put ice on my knee for about 15 more minutes. It was kind of weird. It still hurts really bad, but I heard it's supposed to get better, but who knows.
