Ice your knee where the attachment of the ITB is. This is an inflammation. Like any inflammation take an antiinflammatory - i.e. ibuprofen. Stretch, do yoga, go to a Physical trainer to get stretching, etc. moves that you can do at home. Easy cycling only. Looking at your gait off the bike will do no good; doing orthotics for off the bike will do no good. Every once in a whie a cycling orthotic will help (but it needs to be a cycling orthotic not one for walking or running, they are different) As your doctor said, he knows nothign about bikes.
