Over two months ago I did myself an unusual injury. I jumped down around 5 feet onto a boulder and only the ball of my foot hit the landing while my heel kept moving resulting in my foot flexing further than it should (toes toward shin). I felt a severe jarring in the front of my foot. No swelling to speak of, pretty much full range of movement and no physical abnormalities. My ankle was rather stiff for a week or so but became ok pretty soon afterward. I do however have constant pain in my ankle around the inside malleolus, particularly if knocked or my foot is twisted in an unusual way. Pressing on the malleolus (at the base of it) causes pain.
Hello, It looks like you did not have a clinical examination or X-Ray/MRI/CT of the ankle/foot. Ankle pain is commonly due to ankle fracture, Achilles tendonitis, chronic lateral ankle pain, sprained ankle, RA or OA. You are suggested to keep the affected foot & ankle at rest. You may need ankle support brace, sports tape, elastic bandage, etc. To test your ankle functions your treating doctor or therapist may ask you to do certain activity or exercises. You can take Ibuprofen(Advil, Motrin) or Naproxen(Alive) & Acetaminophen (Tylenol) to get rid of the pain. Your treatment will depend on the severity of the pathology detected.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
