<human>: I was a cross country runner in high school (about ten years ago) and stayed fit through college and grad school etc. About two years ago I had back surgery which put me into the habit of doing all of my cardio on the elliptical at my local gym. While a runner I suffered from shin splints from the get go, ever since those glorious days of junior high track. shudder. 

Two weeks ago I decided to get back into real running (i.e. not on an elliptical) so I pumped myself up with a C25K program and app. I've completed the first week and *bam* the shin splints are back full force. I've taken the rest days and even added in more so I don't understand how I can have an over-use injury after 3 easy runs.  

I ran to the internet and discovered an overwhelming amount of information about running form. For every video on Chi there was one for barefoot, Pose, how to run like an olympian, and then the one guy who says just run however the hell you feel like. Feeling confused and overwhelmed I iced my shins and watched some cat videos. Kitties have awesome running form. 

Chi looks the most interesting to me because of the whole "injury-free running" claim. I did film myself to analyze my form, the video didn't come out great but from what I can tell this is what I'm doing: head, torso upright facing forward with relaxed shoulders. Arms are crossing in front of my body but are relaxed with an approx 90 deg bend. Good ol' potato chip fingers. My hips look like they are getting good extension, but I'm not exactly sure what that is supposed to look like. Foot-strike is midfoot to ball and I'm landing in front of the center of my mass. Is any of this "bad form"? Are there drills or techniques that can help my form? Is cadence a thing a newb 5k-er should worry about? Can changing my form get rid of my shin splints?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: No significant running for years, after three days shin splints. Can changing my form get rid of my shin splints?
