I'm getting old

So I had to go to the doctor on Tuesday because my left knee was causing me a lot of pain for no apparent reason that I could think of at least. So I went to get it checked out just to make sure it wasn't anything serious. Well it turned out being more than what I thought it was, but still not anything too serious. Apparently I have bursitis in my left hip and knee. I have had problems with the hip for a long time...probably around the last 4 years or so but the last year it has gotten much worse, but I never thought too much about it. Anyway, the doctor said that the fluid sacks around the joints in my hip and knee are inflamed, so for the next couple weeks I have to take a prescription anti-inflammatory to see if that helps, but if it doesn't then I may have to have a cortisone injection directly in my hip which would not be fun at all. She also said I may need some kind of physical therapy as well. So I'm crossing my fingers that the medication will take care of the problem and I won't have any more problems with it. So yea, I feel like I'm 21 with the leg of a 70 year old or something.
