I know that you indicated you were doing PT, but I will offer another thought. A really good Massage Therapist. I just got back to the office from my weekly 1-hour of abuse followed by a Cryo-therapy session, and I find it does wonders for my riding comfort. Not the most fun in process as I have asked him what his wish was as my body feels like it will snap like a big wish-bone, but it really increases my range of motion, and then the cryo-chamber at a -220 for a short stint increases the circulation dramatically. Worth a shot!
Oh, and Ewan, i think I can be of some help with the whole wallet thing, you can just send it my way and I will hold onto it for you. :-)
