Hi there! I was diagnosed with posterior tibial tendinitis mid-March after FINALLY getting a referral to a podiatrist at Kaiser. My left foot has been swollen and painful around the inner ankle bone and foot bone. I was cycling a lot last summer and completed my first 100-mile ride in June. A few weeks later, the pain got worse. I pretty much ignored it and kept riding, although shorter distances. I broke my wrist in October while hiking and had to quit riding for months. I thought that would help my foot settle down, but it continued to hurt and swell. I asked my doc a couple different times for a referral and once I got in, I got slapped with "the boot." I am now hobbling around in this gigantic Frankenstein-like boot that is supposed to rest my foot (podiatrist threatened to put me in a hard cast, but I wouldn't have been able to ice or move my ankle). I am not even allowed to walk my dogs. I can't do lower body weight training at the gym because it will engage my calf (which is where the tendon inserts). I am doing physical therapy, but it is very slow going as I am waiting to get in to a sports medicine doc who makes custom orthotics (out-of-pocket expense). I don't see him until April 13. I am terrified of what he is going to say. I am missing all the spring bike rides I signed up for. I am depressed. I have done a lot of research online, and it all says the same thing: It is very common in women over 50 (happens 4 times more often to women), especially if you have extra weight on your frame (and I did. In Weight Watchers now). It usually only happens to one foot. They are not sure why. If you look up exercises for this lovely ailment, calf stretches are a very common one. Tight calves aggravate the tendon. Of course, I never did the right amount of stretching after these rides. I am very good about icing now. I actually enjoy that "frozen" feeling. It certainly helps with the swelling! I see the PT again on April 5. Has your arch fallen on the foot with the problem? This is very common. My foot is somewhat misshapen now, and I've looked at pictures online of what happens when you don't take care of it. Absolutely horrifying! I am with you on this journey, and it has been especially cruel as I was just cleared a few weeks ago for my wrist. Got back on my bike once and then got referral to podiatrist who shut me right down.
