running hiatus

My running is not going that well. During the week I tried a few runs -- always on treadmill, always at a slow pace and always with the same pain in the left knee. The ankle tendinitis has long gone, but developed a case of runner`s knee that just won`t go away. After a run I have to spend the following day taking anti-inflammatories. But when it is time to run again, the pain does come back. I am tired of being caught in the same vicious circle, tired of the pain and tired of taking medicine. I am putting an end to my running this year. I hope that the rest and the new year will do me good.
