So, started couch to 5k three weeks ago. So far, following the plan assiduously, I've suffered shin splints and a pulled calf muscle.
On Monday - start of week 3 - I started out with a slight soreness to my knee after getting back on the road bike on Sunday. After the run - and to now - my knee is very sore. Not swollen, just sore - it hurts on the inside of the leg in the lower part of the knee.
I've iced, elevated and all of that. It hurts when I walk (making me limp), roll over in bed etc. I wouldn't be that bothered*, but (1) I wanted to get fit again and (2) I've got an exercise ECG coming up that I can;t miss....
*I'm hopeless at sorting out injuries with proper treatment.
