I'll ask about gout but the pain location and the constant pain, not in attacks, like gout usually hits you, make me doubt that. Not ruling anything out at this time. The swelling is on the tendon itself and not in the ankle joint, or the bursa sack, where the uric acid crystals would form and aggravate the tissue.
Not enough beef or other high protein food in my diet either. The back of the tendon is the only area in pain and is sensitive to the touch and when I bicycle, especially spinning it does not hurt at all. I actually am pain free when I ride and afterwards. Stretching seems to help the most. I do stretches before and after my rides.
IT band is a real possibility with my history from running so much in HS and college and when I taught school

.
I see the Pain Management doctor Thursday for my check up and I'll ask him to call my family medicine guy so I can get a referral to a specialist. Hopefully at Andrews Institute Sports Medicine in Gulf Breeze. My wife and the walks are not an issue

she and our son both ride with me and will ride before walking. The walk Sunday was a one off to exercise when the thunderstorm threat kept me from riding.
Thanks so much for all of your input and information. it is all being absorbed and added to my list of questions for the doctors.
