Bone & Muscle problems

I got hit very hard while playing basketball on the end on my ring finger and it is swelling. At first there was slight bleeding under the nail but it had now gone. The swelling has lasted about 2 weeks now and is not going at all. It hurts when I try to touch it and I cannot bend the part as much anymore

Yesterday I my bike got skid, and I fell on my right side knee,I'm not able to bend my knee, I have spotted some swelling... Pls tell me what to do

Whenever I stretch/fold my left leg, some crackling sound occurs. It happens only in leg leg. I know the bone sounds are normal. But in my case, this happens ALWAYS whenever i stretch/fold left leg. This is happening for past 1-2 months. But no pain or any kind of discomfort. Only sounds arises. Is this a sign of any serious problem ? What should I want to do next ? How should I improve my bone strength to avoid such issues? Pls suggest. I am 6 feet tall and weighs 70 kg.
