Can't go to sleep

It's 2:53am, and I can't get into sleep.

No surprise. I slept almost whole day today and it's very reasonable that I can't sleep now.

The medication for me knee makes me very sleepy. I want to sleep within five minutes after taking the pills.

And also, my legs don't seem to go much better. That's the second reason I couldn't sleep, I suppose.

For two or three nights in a row, I can't get my right leg straight while I am on the bed. That's a big problem. I remember when I saw the specialist on Tuesday, it could go down all the way with a little push on my right knee by the doctor (although I wanted to scream). But now, there's an at least four to five inches gap till the back of my knee can touch the bed, and I won't push my leg any further, as even without the push, I already feel very painful.

What's next then? I don't know. I guess I will need to see a doctor again on Monday. Buy who? I have no idea.

Some of my friends asked me to visit the emergency so that the A&E will transfer me to a government specialist. I am not sure. I think I am not that "emergency" in fact. But the more advise I receive, the more confused I am. It also reflects how little I know about our health care system.
