Thanks for all the feedback, ladies. My PT did give me some hip exercises to do but I haven't been as diligent in doing them as the foam roller. I think I'll start doing those every day and see if it starts to help. I have not tried riding any other bikes. My cycling budget is already pretty maxed out and it will be a long time before I'm able to increase my bike inventory.
I'll keep you all updated as I get my shoes and pedals. My PT/bike fitter told me to come back for a cleat fitting as soon as I get 'em. Hopefully within a couple of weeks...sooner if I can talk my DH into a cash advance
