Gents,
Thanks for the advice and well wishes.
My doctor is pretty sure that PF is the problem and the symptoms seem to match very closely. He recommended several exercises, orthotics, always wearing comfortable, well-made shoes, and weight loss. I will also incorporate the suggestions made here, particarly Thor's frozen bottle roll (if it wouldn't be for my diabetes, I would use a long neck and drink the beer afterwards!).
Riding is a big departure for me. I've never been a walking Nazi, but I did chide many of my friends when they rode. Perhaps apologies are due. But now that Bob Huntley has given me his blessings, I no longer need to feel ashamed as I now play my golf seated.
Bob, I am sorry to report that my application to that group some time ago was not accepted. Apparently, I just didn't measure up.
Jay F, thanks for the few minutes of levity.
Jim K, my fairway metalwoods are Callaway Steelheads. Though I did not share Mr. Callaway's politics, I admired him a great deal. Long an advocate of bifurcation, I don't view the technology issue in the same way as some of our purists.
Dr. Vostinak, the check is in the mail. There is a company with a store here that does nothing but custom orthotics. I think it is called Just for Feet and they charge $400 plus tax for two pairs of custom fitted shoe inserts (attach to the shoe with industrial strength velcro). I have purchased the drugstore variety and if these don't work, I may try the custom fitted route.
Again, thanks to all.
