Jumping off a form bought back (painful) memories. In the 70's I jumped off a loading dock onto a grass area. However, a water pipe had broken and I jumped into a mud pit. I hurt my ankle. Black and blue from my toes to my waist, but this before MRIs or CAT scans and all they told me was I sprained it. Men's shoes would have me turning my ankle 5 to 6+ times a week, YES A WEEK. I would have to sit down, message it and I would be able to get up and go in a minute or so. 25+ years latter, when they looked into that ankle, they found I had torn my tendon off a bone in my foot. It got reattached in that foot's first reconstruction.Later, that foot had a leaky tendon, and had to have the leak sealed. Then that foot had another reconstruction when scar tissue from the first operation interferred with my blood flow. During that operation they also rerouted another tendon. After that operation I found women's shoes and have had no further issues. Except when I was walking in running shoes and pavement broke off and I totaled my peronral tendon.
Now for the other foot. In the mid 80's I hyperextended the achilles tendon playing tennis. Had to wear a 'balleria' cast, a cast with a 3 inch stooped built into the heel. Couldn't wait to get that cast off. Then in the nineties, I stepped into a gopher hole just before leaving on a family vacation. When I returned, I had both ankles looked at. They wanted to work on both ankles, but I choose this one first. I had broken a bone inside my ankle sack. They also tighten my tendons too. Then I stubbed my toe, I meaning really stub it. I wouldn't get straight and would just stick straight up. In that operation they reroute tendons and took out a hammer toe joint, then inserted 6 inch rods/pins through the toes. Weeks later when they pulled those pins out I screamed at the highest pitch ever.
@mlroseplant try soaking your foot in Epsom Salt and see what happens.
