I hope it isn't the start of something new too.

Here are my thoughts for what they are worth. Having gone through 3 foot surgeries and a boatload of rehab have made me learn a bit too much about this kind of trouble.

When you say this is only with shoes off, during pronation, mid-stance and toe-off that sounds like a a lot of dynamic tension on the foot. The nerves are pulled at maximum stretch when the foot is flat on the floor, especially if your inner ankle tends to lean in which adds even more stretch.


You may need to wear a little something around the house that gives your heel a slight bit of rise, even just a half inch to take some of the tension off. If that gives relief it's good info to have and may be all you need to do.

As to why now...who knows? I think Mrs. D's podiatry suggestion is a good one or if you prefer a Foot and Ankle orthopedist. Note any changes to them that might be pertinent such as weight loss or gain, exercise changes or circulatory issues that could be causing any swelling.

Good luck,
