I didn't stay in a Holiday Inn Express last night, so don't know how much I can help. About 15 years ago or so I thought I had it. Self-diagnosed like you with Dr. Google. Very painful. With me the pain was very, very intense first thing in the morning getting out of bed. All night resting and then getting up was awful. Still pain while moving/walking, but not as bad. Finally after maybe a month or more it started to get better till it wasn't there anymore.
Then two (?) years ago it happened again. Wasn't sure if all the symptoms were the same, but the pain in my foot was horrible. Couldn't figure out what I had done if anything, but a couple days before it started hurting, we had gone to the Neil Armstrong Museum in Wapakaneta, OH on the Saturday that was the 50th anniversary of the moon landing. Hottest day of the year so I wore sandals. Huge crowd so we had to park a mile or two away and walk...standing in lines....lots of walking that day. So when it started hurting I blamed it on wearing sandals and being on my feet all day. And like the last time, the pain went on for a month or more and slowly subsided.
But in thinking about it while going thru the second episode, I noticed that both times I had been working in one of our rental properties...drywalling, painting, carpentry, etc. Parts of that building has concrete floors and I had been kneeling down a lot while working...thus bending that foot. So, now I wonder if the first episode, that I thought was PF, wasn't really maybe stretching ligaments or something in my foot. But, strange that it has happened twice and the same pain was so intense. But, and I drive the Mrs nuts (who was in the healthcare industry, so..go to the doctor..stay off your feet..etc), there's always something that has to be done so I kept on going, working thru it.
Y'all have a good Saturday.
