Sick Sick Sick

I'm sick again. This is a knee's time. I have a gastritis and trouble with my wisdom tooth. Today, my knee is sick. When I was young, I sprain an ankle. I didn't went to hospital, so I always felt a dull pain on ankle. Few years later, I felt a dull pain on knee too. I think that is not a big problem, but that is my mistake. I can't sleep at night. Sometimes I wake up because of pain. I'm very sad. I think I have to go hospital.
