Very good article! Although the article states the injury as being rare, it seems a lot of runners get it. I never had a problem with running until now – in my 40’s. After a few years off, I started to gradually get back into running last year. 2 months went well but when I started pushing myself, my hips started hurting. I continued running through the pain until my right foot also started hurting. Then my knee and then my lower back and then my hamstrings high up were hurting. With 5 areas of pain, I went to a Chiropractor and he gave me a right foot heel lift. My knee pain was gone the next day. Eventually my foot got better. My hips got better and lastly, my lower back got better, For about a year, I still have high hamstring pain and just keep my strides short. I did this for months pushing myself further with low pain to no pain. I finally decided I needed to do sprints and fartleks if I was going to improve my time. That’s when my high hamstring flared up so bad I could barely walk. I’ve been sitting on a tennis ball at my desk job and also when I drive, stretching like crazy. I’ve started pilates and core strength training. I’m trying to refrain from running and just cycle until I can get back to running full stride. After a year of hamstring pain, I’m finally giving in to rest and recovery. Oh… I’ve found that biofreeze helps alleviate the pain so I’m now using that daily to help the recovery faster. I refuse to have any type of surgery… Every injury I’ve ever had with just rest and rehabilitation, I’ve been able to overcome the need for surgery.
