I have been dealing with a lot of the same issues that have been shared with on this post. I am a college runner who usually runs around 70 miles during the season. My bad leg is my left one. I will start running and for a few minutes everything is fine...normal. I get about 10 minutes into it and my leg starts feeling almost loose and all over the place. It literally feels like I can not get it in front of me in time. In my opinion its almost a whipping sensation to get it in front of my body. Like others when I run on softer things like grass I can "last longer" then when I run on the roads. I barely ran any cross this year because of this problem. I took a month off after cross to see if that would work and when I started running nothing changed (still awkward).Now I am starting track and thinking that it may continue to ruin things.
On the Doctor side of things I have tried some stuff. I first got a MRI of my hip with the dye and x-rays and nothing was found that was in september/October. during my month off I got a MRI and x-rays of my back and nothing was found again. So I also started working with a PT. Some of the things we have done seem to help but eventually I start having this trouble. Lot of band excersises and step ups and even weight lifting. Nothing has really worked or gave me the feeling like it would have positive lasting effects.
From what Neliah2507 said about his symptoms it sounds like I could have a laberal tear....(which I have thought for a long time but since nothing was found in my hip i had no case to base it on). Is there a possibility that I may have it and the MRI missed it? How often does that occure? again I also have absolutely no pain at all just not able to run does that corrospond with a tear? Should I get a second Dr. Opinion? Any answers or help would be awesome....I just want to run again!
