Causes
IT band syndrome occurs when excessive friction occurs in this part. It can be caused when the band is overly tight and rubs against bone. Repetitive movements that lead to an overuse injury are often the main cause. The injury is particularly common in runners and cyclists. However, it can also happen in those who use the tissue repetitively, such as sitting with bent knees for extended periods, wearing high heels, or walking down or upstairs. [2]
