It's getting better; and it's getting worse

I am on the anti-inflammatory drug for the third day. My knee was getting better yesterday; but it's getting worse today. The pain is on even if I just sit down for the whole morning to practice my calligraphy.

I am still thinking what makes me have Osteoarthritis. It's usually on people at least 40 years of age (well, there are still quite a number of years to go); who exercise vigorously (well, I seldom exercise); who are over-weight (well, I am fat but I am not that fat yet). So I really don't understand why I got Osteoarthritis.


Let see if it will go better after I finish the anti-inflammatory drugs.
