Thank you! 
I ran today and there was a sharp pain at the bottom of my leg, from my ankles (which where also hurting a little bit) to just below my knee. It stopped me from running an extra mile, and later on to the end of my session it started to hurt on the side of the area as well.
Then when I stopped to walk it hurt similar to a headache, it was a sudden sharp-numb kind of pain and it hurt so much that I actually said "ouch". I stopped running because I thought to myself that I don't want to injure myself. My legs could have been tired as I slowed down so I could run longer.
My running shoes are the Nike Air Citius 2, but I've never experienced this sort of pain before. Do you think it could be my running shoes?
I have a poor running form I land flat on my feet , I don't know any other way to run! Can you please tell me how to run properly?
I run on slabbed pavements, so I run on a hard surface. I'm worried that I have shin splints as I was really getting into running, I was enjoying it!
If I do have shin splints how long will it take me to recover, hopefully a few days?
Or do you think it could be fatigue?
If I do have shine splints would rowing and swimming be good cardio activities?
Thank, Akshay.
