I think I'm currently suffering from the seemingly popular ITBS. I've been told I'm a neutral runner but due to being extremely inflexible I'm actually pronating. The Physio has recommended lots of stretching (ITB, Quad, Hams, Calf, Soleus(?)) so hopefully this will work.
She also mentioned that a supplement called Glucosamine is having very good reports for repairing cartlidge injuries. Has anyone else heard this and is the general opinion from other people's Physios that stretching alone rather than orthosis are the answer to ITBS??
