Hello I was at work on a ladder and turned and felt something pop in my foot and now have a lot if pain in foot. No swelling. Very tender?

Pops. Could be a lot of things, including dislocation of a joint, tendon, or ligament. Also could be a tear of a tendon or ligament. Lastly, it could be a fracture. I would have to know where exactly in the foot it is tender. I would also get an x ray. In the meantime, rice therapy (rest, ice, compression, elevation) until you get in to see a podiatrist.
Need infor. Where in the foot does it hurt, how long ago. Best to be examined by a podiatrist.
