My right knee has been hurting me since the Park City Marathon.  That worries me a little bit for 2 reasons:  1) my right knee is my 'good' knee (the left one is the one that always is injured) and 2) I have never had a knee injury on the inside (not under the knee cap) of the knee before.
I tried to take it easy while running last week (ok – most of the time I tried), but it just seemed to get worse and last Saturday's run on the trails pushed me over the line.  Sunday morning I woke up to a very sore knee and it had waked me up off and on during the night when I straightened the leg.  I took Sunday and Monday off from any leg workouts, put a neoprene brace on the knee, started anti-inflammatories (thank heavens for Vitamin I) and did some icing.  I also scheduled an appointment with a Sports Medicine doctor.
Today the knee was feeling somewhat better, I could go up and down stairs without too much pain.  Signs the knee is healing.
This afternoon I met Dr. Jamie Longe.  It is always nice to have a doctor that actually appears to understand the stresses of marathon running and training and doesn't automatically tell you to not do what caused the injury.
Diagnosis:  Tendonitis in the hamstring attachment, Bursitis, and a pinched Meniscus.  The Meniscus is the concerning factor.  If it starts swelling or the pain gets worse, then we have to consider a torn Meniscus.
Treatment:  Anti-inflammatories 3x a day.  Topical anti-inflammatory ointment 4x a day.  Ice for 20 minutes after working out and before bedtime.  Stretching after running – he gave me 3 variations of a quadriceps stretch and 3 variations of a hamstring stretch to do.  Running is ok. I just need to be careful and not run on trails for a while and not do exercises that cause that knee to have to pivot quickly. Brace it as needed for support.
That being said – with the doctor's permission – I am going to go for a run.
