My knee is mad at me

I swear my whole body is upset. I think it's on strike. I've been exercising for 1.5 month now, running every Tuesday and going to the gym every Friday. It seems not to like it!

Last week my bottom-left wisdom teeth started to grow again, digging its way up my gums. I could not open my mouth for 3 days. Barely enough to eat. But it's over now and no, I don't want to have them removed... ;)
Now, my right knee has been killing me for 2 days. Tuesday I tried to run and after 20 minutes my knee started to burn at each step on this spot:

I went to see a doctor who has a degree in sports medicine and he doesn't know exactly what it is. Apparently my right tibia is not in line with my femur but it shouldn't be very serious. He gave me a gel to put on the aking spot twice a day and some anti-inflammation pills...
It feels a little better now, a least I can walk in the afternoon. In the morning it hurts like hell. The worst thing is stairs. I so can't do stairs in the morning. The bad part is that I live on the 5th floor (american's 6th floor)... with no elevator.

So no more running for at least a week... :(

Can I also have a big headache to go, for tonight?
Thank you.

Apparently it's a tendonitis... and still hurting...
