For the past week I have been suffering with unbearable pain due to shin splints (they feel bumpy which I've never had before). I run 4-5km a day usually, but I have been doing this for few months so I don't really understand why this has just happened. Does anyone have any tips on how to treat it as I'm barely able to run 1km without extreme pain and I need to run as it helps with my CFS. I've tried painkillers and icing it but nothing seems to help, so any suggestions ? Thanks!
