I have a referral and an appointment at silly o'clock tomorrow morning. In the words of my doctor, this physio practice is "old school" and focusses on treatment that will get me back running faster. The treatment will be painful as all heck, but very effective. The toss-up was between this or a longer, more drawn-out type of treatment with more focus on the long-term stuff. I figure that I'll go for the short-term effective treatment and get a second referral for the extended, long-term work later on. Both. Not either.
The short of it is that the doctor thinks is is fairly acute IT band syndrome, exacerbated by going so hard on the bike before running each triathlon, thus tightening them right up at the time. He was almost shocked to hear that the pain comes on so quickly into the runs, which was almost a relief to see.
We'll see what tomorrow morning's assessment brings.
